Aaaaahhhh..... I see what you did there...
I like that with perl, I have the flexibility to find correct syntax by simply trying out what makes sense. When I do have to actually look something up the answer was usually pretty close to my guesses.

You have bought into the bigscript mentality of saying 'my' before a $variable.
It's like I'm watching the destruction of c all over. No, I'll not go quickly into that night. I'll rage, RAGE against the existing thing.
I just like it because it lets me reuse simple variable names when in subroutines or loops. Kind of got in the habit of using it where I didn't have to.
Also, use strict keeps me from getting sloppy, and it bitches if I don't "my" my variables.
Yeah, that's what the nazis said!
"Verkunft ein 'my' er variable ein gesacht!"
was their exact phrasing, if I'm not mistaken.
UPDATE: Ok, I admit it. I've no idea what those German words mean. But I will say that using 'my' in a perl script is tantamount to writing in c++!
Why not write an object, hippie!
(just kidding on the last comment)
It's funny that I was more offended by the object comment than the hippie comment!
I completely get what you're saying, but this is (rough) production code, and if I require a function or even a *gasp* object, I'll have to bite my tongue and use it... Lest some perlmonger greater than I view my source (in an official capacity) and loudly proclaim "This guy doesn't know shit! Why are we using the code this company has provided!?" :x
