Probably. It's hard to tell without the code.

IMO, the easiest thing to do in the log run is to change
"stuff.pl" into a module called (perhaps) "stuff.pm". The you
can "use" it. You might end up with something like this:
package stuff;
require Exporter;
@ISA = qw(Exporter);
@EXPORT_OK = qw( foo );
sub foo {
return 'foo';
}
1;
It would be called like this:
#!/usr/bin/perl
use strict;
use warnings;
use lib '.';
use stuff 'foo';
print foo();
__END__
Read the docs for Exporter on how to export functions and
variables easily. Read perlmod for more info on writing modules.
