Sorry this is sorta off on a tangent, but why the hostile attitude towards subroutines?
Obviously, implicit modification of globals CAN be a Bad Thing™ if it's done in such a way that it's hard to follow, but if you're writing a small script,and pressed for time, and you're careful to document what you're doing, it's a timesaver. What other problems does it cause that I don't know about?
I've always thought of subroutines as just that - named blocks - and to me, that makes them a handy way to document or re-use code, even if they don't take args or return anything explicitly.
Have I overlooked some major diabolical evil that subroutines are capable of without knowing it? Or is my perl style just lacking for want of experience?
