Yes? So you move the call to main below the block and you still don't need it in a BEGIN. You would squash a normal closure by doing this as well. The BEGIN isn't needed unless you design your script so it is. 

#!/usr/bin/perl -w

use strict;
use vars qw($sub);

#exit main(); # Useless use of closure below if called like this
          # BEGIN block would be needed in this case.

{
    my $time = time();
    $sub = sub {time - $time};
}

exit main(); # No problem, no BEGIN needed.
sub main {
    print &$sub;
    sleep 2;
    print &$sub;
    return 0;
}
