in reply to Overloading '{}' or 'sub'

See Scope::Guard, which is designed to do exactly that, you create it with a subroutine to run when it goes out of scope...

use strict; use warnings; use Scope::Guard; sub foo { my $blah = shift; my $sg = Scope::Guard->new( sub { print "This runs at the end of the scope\n"; } ); print "Doing some other stuff now...\n"; }
We're not surrounded, we're in a target-rich environment!

    Wasn't operator overloading designed by Satan for evil C++ programmers to torture each other in the hell that they have created for themselves. Or something?

[LanX]: Question: starting a script from an icon in Windows, but after C-c the window closes ... what I want is to restart in the cmd.exe. Recommendations?
[Corion]: LanX: What do you mean by "restart in the cmd.exe" ?
[Corion]: Do you want to launch a script and keep the command prompt/console window open?
[Corion]: Do you want to wait for a key press before closing the window?
[LanX]: I want the command line in the history
[tye]: -Mouse
[Corion]: Option a) would mean launching cmd.exe /k c:\path\to\ batchfile- launching-perl- script.cmd. Option b) would be to add pause as the last line of said batch file.
[LanX]: First day after holidays ... and already stressed by the fact that colleagues changed stuff without communication ... apparently I'm the only one trying to fight entropy
[Corion]: LanX: The command is always in the history if you typed it in before. If you didn't type the command into the command line, it will not be there. I think there is doskey which can stuff command lines into the history
