I'm curious if there are any side effects to doing the following :
#!/usr/bin/perl
use strict;
use warnings;
my $var1 = "test1";
my $var2 = "this is not test2";
{
my $var2 = "test2";
print "$var1 - $var2\n";
}
print "$var1 - $var2\n";
What I'm trying to do is create a temporary variable within the main
body of the program. I don't want that variable to stick around after I
use it (which is directly after I declare it) ...
In most cases, I'll be using "unique" variable names within that local
block. The idea is that I want to release the memory associated with
those local variables without carrying them around. The rest of the
program definitely uses a lot more memory, but good memory management
dictates that I release it when I'm done with it. I never need that
inner $var2 again, so why bother leaving it around?
