A New Kind of Fail?

Who names their language Noop[^]? No-op, No Operation, i.e. nothing's gonna happen here. Why oh why would you name a computing language this, and then expect people to rush over to it? Are web "developers" truly so clueless that they are unaware of what "noop" means? I go to the project's web site and of their two "blogs" that they list, the first link just collapses in an error! In their list of "features" they list that they are all for "Immutability" - why? You can only change something once? What the hell is up with that? And no implementation subclassing? Have I missed something here? Is there something I'm being blind to?

In other news, my new language "SHíT" (pronounced "just purrfect") hits the shelves tomorrow. What do you mean "dependency injection support right in the language"? Does that mean it has (*GASP*!) interfaces and (*SWOON!*) constructors receiving parameters or even (*ICANTBELIEVETHEYDIDTHAT!*) public properties? [edit] On second thought, maybe .NET has put enough pressure on JVM performance that it's time to build a nice language on top of it.
Personally, I love the idea that Raymond spends his nights posting bad regexs to mailing lists under the pseudonym of Jane Smith. He'd be like a super hero, only more nerdy and less useful. [Trevel]

A focus on Immutability means they're guzzling functional koolaid.
The latest nation. Procrastination.
So in functional languages (I have only a very basic understanding of Lisp) if you have objects, you are not allowed to modify them at all? That seems silly to make as a unilateral rule. But what the hell do I know, I just program for a living.

I saw that too, and was a bit clueless as to what they actually meant by it. But it certainly fills in the buzzword feature set!

I had similar feelings a few days ago when I tried out MSP from those nice people over at JetBrains[^]. It's not them, as such, I like Resharper, which is why I decided to give MSP a go. I followed their tutorial and I'm afraid that I just don't 'get it'. To me it seems to complicate things by a factor of about 10. As I say, it could just be me, but I would be interested to know if anyone else has tried it and thought it useful.

AIUI, I've never used one myself, when you need to change an object you end up creating a new one from scratch. This <magic happens here> allows the compiler to produce massively parallelizable code.

So I have foo. Then I write
foo.count = 10;
And under the hood instead of just modifying the count value (or whatever the hell it is) directly, a complete new instance is created with it's count set to 10, and then, presumably, the old foo instance is tossed? That seems like an insane amount of extra work just to allow for thread safety, which is what you're alluding to, right? //edit Actually it's worse than that - if they copy the new instance, they have to copy ALL of the state of the old instance, how does it handle complex objects, references to other objects, collections, and all that crap? Seriously nasty.

It's a completely different programming paradigm. You simply don't do
foo.count = 10;there. And no, you don't have to copy ALL state (references to other objects). Because objects never change once created, it's perfectly safe to reuse the existing objects. The reason whystringin C# is so easy to use is because it does precisely this. Immutable types are generally easier to work with. And there are efficient implementations for most data structures. There's no need to create a full copy of a collection just to remove some element in it; instead the collection is interally arrange as some sort of tree and will share subtrees that didn't change. Of course, for some purposes you need mutation. How those cases are handled differs from language to language. In "pure" functional languages, you might use something like the Haskell "State" monad to solve this. In other languages (like F#), it's perfectly possible to modify existing objects just as in C# (but of course you lose all benefits of immutability as soon as you do so). -

You shouldn't really have objects. That implies state. :laugh:

You're assuming that usage of objects implies they will have a state. That may not be always true in practice. :laugh:

As far as I'm aware this isn't new, what's new is people expect others to actually care. I've seen a few projects like this which started out as a 'Well someone else in the world has to think this is a good idea too, I'll put it on the Internet'. Generally that idea has proven wrong. Could just be the college crowd is more prone to it, haven't run into half as many instances of this since graduating.

No, they may even be functions themselves. :)

Only in pure functional languages do you have complete immutability. No state, just what you pass around as parameters. Tail call optimisation means that a recursive call is really a loop, so a recursive call with modified parameters is equivalent to looping with modified state. Big gains w.r.t concurrency - no state means no shared state! The compiler can do more precise reasoning about your code. I tend to program a lot in a functional style in C++ - replacing an object can often be a lot more reliable than updating state.
