Re: Why use strict/warnings?

Why use strict?: (warning: I might be dead wrong about this, but this is how I understand it) Assume you have a subroutine, and you set a variable called $mystuff. You also have a variable called $mystuff in your main program. use strict will keep you from running the program if you try to use $mystuff in your program without indicating which $mystuff you're talking about. This sounds harmless, but it's harder to figure out without using strict since you can't tell where your variable's getting screwed up - the subroutine or the main program. End result: Strict makes sure you keep your variables where they belong, rather than referring to some other structure (subroutine, module, etc.)'s variables.
Why warnings?: They help you figure stuff out. From experience, it's a lot easier to fix your program when you're writing it, than once it's already been installed and otherwise working!
