The main problem here is that just because the command option can accept [$main => 'destroy'] as a configuration for an internal Callback does not mean that the same syntax can be used standalone outside of that context. What you're looking for is: $main->destroy like the following stripped down example. 

use Tk;

my $main = MainWindow->new;
$main->Button(
   -text => 'Submit',
   -command => [\&Submit]
)->pack;

MainLoop;

print "Script continues after mainloop terminated\n";

sub Submit {
   print "Submit called\n";
   $main->destroy;
}

Destroying the MainWindow allows the Event Loop created by MainLoop to terminate, allowing the lines following MainLoop to execute.
