Been there, done that. :) It's strange how people immediately blame the use of properties, or the case sensetivity of the language. It's like everyone is running around with a protest sign, just looking for a good spot where they can stand and wave it... ;) I have used the wrong name just like this a few times, and every time it was because I was using intellisense and chose the wrong item. Is the conclusion then that intellisense should be banned? Of course not. If everything in a programming environment that could possible be used in the wrong way should be removed, then we'd be back at writing code on punch cards...

Actually, we didn't write anything. We used typewriters of sorts, that really did punch holes in the cards. Beat the crap out of playing with all those toggle buttons, though. :-D

Not the only reason. It is also considered bad writing to mix cases. Ask an English Major. This must be at least partially a "readability" issue and we are not even talking "code" at that point. Also all caps are difficult to read because we process the character hights and read faster. All caps slow down that process by eliminating hight variation. This indicates that consistency is optimal to readability. tRy ReadIng soMthiNg lIKe thIS aLLDaY LOnG aND sEe hOW yoU LiKE IT! With something as specific as "code" I think the problem is increased. Therefore I am sticking to the "readability" issue as supporting case-sensitive languages.

In German, only the first word of a sentence, nouns and names are given upper case (might be a few other cases (no pun intended)). The Upper Cases Are Not All Over The SentenceS. :)

If the language doesn't, some project manager will through coding standards. What I'd like are non-ascii characters in programming languages. That would be far more usable than case insensitiveness.

:) Sure, as long as the "details" are not hidden so well that you mix them up and end up with a stack overflow.
Maybe you should just avoid all languages that allow any sort of recursion. :laugh:

No, I just avoid methods that look like data members ;P

They can have my properties when they pry them from my cold dead hands.

I'll admit I've used case-sensitivity to distinguish fields from the properties that represent them. I've never had this recursion problem and it doesn't seem like a big issue. Seems like it should be easy to track down. I don't even think it is necessary to have some silly convention like junking up field names with an "_" or "m_" prefix (or even a "look_out_this_here_is_a_member_variable_and_the_other_one_is_a_property_reference_so_do_be_careful_" prefix). I had more troubles with unexpected recursion when overloading the comparision operator. That's where you discover a strange dichotomy between reference variables and operator overloading, in that operator overloading kind of lets you treat variables like they are values when they are really references. It works out okay in C++ because you really can do that, but in C# it is trickier.

This is one of the reasons that I use underscore to prefix fields. They make it so much easier to spot.

I was not bitten by the same bug, but I started doing it a couple of months back. Reason? They're easier to spot. :)

Properties (with appropriate gettors and settors) are excellent assets to the language. I would say case-sensitivity is also required. The good glue is a a good consistent programming standard (aka) coding standard which would make a cleaner reading of the code, finer debugging, elegant troubleshooting and expedited resolution to the problem.

Hehe, I'm still using m_ prefix in my code, for member variables. I got a fellow coworker who goes further and uses l_ prefix for local variables and p_ prefix for parameters... :doh:

I had a problem with a web application killing the dev server built in to VS2005 with stack overflow errors and I couldn't find the problem. I went so far as finding every for, foreach, and while loop and putting a counter in them that would throw an exception with the method name in the message if it looped over 1000 times (which none of the loops should do in this app). The problem all came down to one capitalization error that I didn't see even though I went step by step through execution with the debugger...
public string Name
{
get { return this.Name; }
}
private string name;Obviously the "this.Name" in the property should be "this.name". I felt like a moron when it was over.

Classic, it makes me think that it is about time the compiler warned you about this sort of tight recursion where there is no possible exit. :)
