Re^2: Best practices with globals and subroutine arguments

I'd probably use "global" variables. I wouldn't say on Perlmonks ...

You obviously know about scoping, about the best practices and when its ok to break them; you're an expert.

How often do you use globals to avoid de-referencing references, and does that simplify things considerably?

The OP indicates the variables are not modified inside the subroutines. For the POV of the subroutine, the variables might as well be constants. How often do you use "global" constants, and does that simplify your code instead of passing them around in each subroutine call? You obviously know about scoping, about the best practices and when its ok to break them; you're an expert. I find this a bit insulting for the OP. It suggests the OP is an idiot, or at least needs to program with his training wheels on. I do not with to make such assumptions.	[reply]
