I hate recent C# versions!
-
The "best" part is that, like `out`-with-declaration, the declaration pollutes the scope *surrounding* the `if`. That's also annoying about the old pattern of using `as` and checking whether the result is `null`, but this new syntax syntactically suggests that it solves that long-standing annoyance and it doesn't.
I'd agree - the scope should logically be limited to the
ifblock. It seems strange that it wasn't really ..."I have no idea what I did, but I'm taking full credit for it." - ThisOldTony "Common sense is so rare these days, it should be classified as a super power" - Random T-shirt AntiTwitter: @DalekDave is now a follower!

It does the null test, declares the new variable, assigns the value and completes the
ifin one statement. Think of it like the very old C way of doing aforloop:int i;
...
for (i = 0; i < 10; i++) ...As opposed to the simpler version that was added in C99:
for (int i = 0; i < 10; i++) ...
People complained that that was a kludge back then as well! :laugh: I was a sceptic, but once you are used to it you probably won't go back.

You'll have to learn them, if you want to read new and foreign code-bases, so little choice there. There's a trade-off though, and I can't see how much value they add that can justify the confusion and the costs. As an industry, we'd be better of with consistency and fewer changes, saving them up for a few years and come with a decent change. Not just more sugar every umpteen months; if it were as interesting as animated icons on the desktop, then I'd be all for it, but it not even half that good, if anything, it's contra-productive and generating more costs than it is adding in value.

Or can't we kill the beast because some of us aren't trying? I know a developer who'd still start new VB6 projects in 2022 because that's all he knows, it works and clients are satisfied. Why learn something new when the old still works? This person also uses hidden controls on a form to store values, instead of using variables like the rest of us do. Also, because it works, so why try harder? He'll be retiring later this year and he gets to keep all of his software and clients because no one, and I mean no one, could ever unearth whatever it is that he built. There are plenty of people like that, sort of technical quakers. We had technology in 1999, which is what God intended, and we need nothing newer.

That's exactly what happened and why VB6 still exists.

Needs to apply to an
elseif present? :~Nope - because if it isn't that class, it should be at best
nulland thus unusable in theelse:-D"I have no idea what I did, but I'm taking full credit for it." - ThisOldTony "Common sense is so rare these days, it should be classified as a super power" - Random T-shirt AntiTwitter: @DalekDave is now a follower!

I agree, yes, that's good, though I don't use C99 either. On the other hand, I notice that there is no similar syntax for
while:-D .While is more of a "general purpose" loop construct, most commonly used with things that have been already constructed, like file pointers, linked lists, strings I think. It's less likely that you'd need the declarative part since a
whileloop doesn't have an initialisation phase like aforloop does."I have no idea what I did, but I'm taking full credit for it." - ThisOldTony "Common sense is so rare these days, it should be classified as a super power" - Random T-shirt AntiTwitter: @DalekDave is now a follower!

Which maybe I want! I can use
nullbetter'n anybody! (OK, probably not.) But what if the syntax allowed the use of the null-coalescing operator as well! Way hey! -

But it could! Except then it might just be roughly equivalent to a
foreachanyway. :sigh: -

You can't keep anything nice. (I've only ever dabbled in C++ .) I may need to look at D again.

This C# discussion is an age old one. Remember: if it ain't broke don't fix it. Change is the enemy of working. Better is the enemy of good. Perfection is the enemy of good. Static = no growth, no growth = death .... on the other hand when a fix corrects something broken, its a good thing. When change = easier, its a good thing (sometimes) ....

Hmm, rarely. And something which merely "saves keystrokes" is best avoided. I can save an awful lot of keystrokes just by not writing comments and documentation.

Agree. However they do not just save keystrokes, hence I like the features listed here. Reducing the risk of errors (like the switch expressions) and reducing the amount of code that is not clearly expressing the intend of your algorithm (like ?. and ??) Is a clear benefit for me. I can even get behind the minimalistic stuff, once they expand it to cover all classes. I have no need for one single class to look completely different. But I guess they will eventually realize the main use case for C# is not only doing cool demos at conferences and expand it to us who have "complicated" programs needing two or more classes.

Speak for yourself. I, for example, love ?? and switch expressions for making the syntax more readable, actually. They are concise, that is, there's less syntax to achieve the same thing, meaning less overhead to parse when reading.

I believe they are competing with JS and python, because programming Meme always noted that python is fast in a single hello world sample, And others are not. The things I'm not sure about is why companies such as JetBrains also support those bad manners, and force users to change code to some of these style, while they just could ignore the user style (that may depend on the surranding and could change readability regarding to that)

i hope it does not sound patronizing for me to i say that i "love" the discussion of "I hate recent C# versions" :) what a pleasure for an old man about to get new eyes, to savor the illuminations of many of CP's brightest-bulbs. Kornfeld's signature quote from Einstein: "Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid." Did make me chuckle ... as I thought of the tree-climbing mudskipper fish whose evolutionary history is detailed in Richard Dawkins' magisterial survey, "The Ancestor's Tale." (see "The Lungfishes' Tale").
Quote:
Another common name, ‘climbing fish’, comes from their habit of climbing mangrove trees looking for prey. They cling to the trees with the pectoral fins, aided by a kind of sucker which is made by bringing the pelvic fins together under the body.
That boomeranging thought leads me to ponder if the evolution of C# ... leads us to believe we ... are ... smart. Is the "destiny" of C# (my favorite grab-bag of syntax and functionality masquerading as a "computer language") to have as much junk in its DNA as we, Homo Saps, do ? cheers, Bill
