Care to explain why they are there if they are evil? I sort of like having a decent check that the arguments to my functions are sound (most languages provide this), and have only adopted using them in Perl lately -- despite some controversy. Coming from a C/C++ background, forward declarations are considered a good thing.
Is it true that in Perl a forward declaration is essentially a definition, and thus you run into problems with defining functions that never have a correctly defined body at a certain point in the code? That's the only reason I would think would make them a bad design choice.
I will accept the wisdom of folks in this thread saying "don't do it", but I'm a stubborn beast and I usually need to know why I am or am not doing something.
