ICK. Don't define %GlobalVars in the function! Doing that makes you
define it EVERY single time you call the function.
# globalvars.pl
use strict;
my %vars = ( PathA => '...', PathB => '...', ... );
sub get_var {
return %vars unless @_;
return @vars{@_};
}
Caveat: "globalvars.pl" is a BAD name for that file, since they are very
UN-global variables.
