hello
knowing the "my" initializes a var doesn't tell me much about a case in which:
for my $index (@array)
{
my $var = whatever;
...
}
(as I plan on doing)
can doing so cause any problems ? (pretty sure it does in java, but can't remember nor try)
will the $var be re-initialized for every cycle of the loop,
or will perl be "smart" enough to preform the line without the "my" after the 1st cycle ?
and if it would re-initialize, will this cause any visible problems or merely cause some memory inefficiency ?
(and yes, I am planning on using both strict and warnings)
also, if this does cause a problem is there an alternative to "my" that will behave as mentioned ?
I'm so tired of throwing vars and their "my" back to before outermost loop (just in case).
I know I can just run some tests and try to figure it out myself, but I didn't want to risk having it work for some cases and confusing me later for others, under the false assurance that it's bulletproof (and so I'm here ^^)
thank you very much
