in reply to Press enter to exit

A modification to kcott's case 1:

This will always prompt you to press enter, no matter how the script exits, even if an error is encountered.
This can be useful if the script is running in its own window which closes when the script exits.
use strict; use warnings; # ... my $x = 1 / 0; # ... END { print "\nHit enter when done: "; <>; exit; }
Illegal division by zero at D:\stuart\play\temp\ line 6. Hit enter when done:

LanX wouldn't update system Perl!
[Discipulus]: prathap keerthipati might be it is better to install an alternative Perl instead and do not touch the system one
[LanX]: see perlbrew for alternative Perl installations
[marto]: unless you know exactly what you're doing an often saner option is to simply build another Perl rather than replace the system one
