Here's a topic for discussion:
Coming from C++-land, I've always been taught over and over again that all
subroutines/functions/blocks/etc should have only a single entry point and
a single exit point. "It's just good programming practice." But now in
the world of Perl, I've observed that a "Perl-ish" thing to do is to place
multiple return/exit/etc statements in certain blocks of code or in
conditional blocks. (Then again, maybe it isn't Perl-ish, but I've had to
sort through many perl scripts like this.)
I guess I'm just curious to know what other more experienced Perl
programmers think about this. I still adhere strictly to the "one way in,
one way out" philosophy, mainly for the sake of readability. But I
understand how much easier it can make a programmer's task to write
something like "if (some condition) { exit; }"
Also, I was wondering if exiting prematurely like this from a program has
any adverse affects on the execution of the program.
Thanks,
Kurt
