>Over the years I've seen maybe half-a-dozen cases, in other peoples' code, where the programmer carelessly used different cases when referring to the same variable or other symbol name in a case-insensitive language. The code was always sloppy, so now it's a real "Danger, Will Robinson!" signal to me.

If you code like your language is case-sensitive, even if it isn't, you never get burned.

OK, self test for everyone on this thread: when you type in command window, how do you type something that's otherwise camelcase? Say, you have your code stopped in the debugger, and you want to type a name of a variable. How do you type?
