Re^4: Why does this sub grab the whole hash

in thread Why does this sub grab the whole hash

Oh man - enlightenment just hit me. Looked over my code and now I got how this poor array was filled over and over again with some quite random stuff in the different parts of my script. Really bad idea to use a subs like this with a globally defined array.

And that's why people always recommend to `use`strict`;` -- it complains about undeclared variables, so it forces you to think about where to put the declaration. And you only put the declaration outside the subroutine if that's your conscious choice. Perl 6 - second systems done right	[reply] [d/l] [select]

Really bad idea to use a subs like this with a globally defined array. It's a really bad idea to use subs (or anything else) with a globally defined, non-constant anything unless, as moritz has written, it's your conscious decision to do so — and even then I'd think twice about it.	[reply]
