[perldigious]: karlgoethebier: Well it is a pretty old and complicated (for me) bit of code I wrote (poorly by my current standards), so I'm expecting everything to break when I add the scoping and find out what else is undesireably scope changed. :-)
[perldigious]: Ah, thanks choroba, that sort of thing was precisely what I was wondering when I asked.
[perldigious]: I didn't want to tie up memory unecessarily basically, I wanted to "delete" it specifically to free it up, and wasn't sure I was even accomplishing that.
[stevieb]: perldigious You should start by writing some unit tests. That'll ensure current functionality doesn't break with changes.
[choroba]: unit tests++
[choroba]: The only problem you can't solve by adding more tests is the problem of having too many tests.
