Wait. This is not about efficiency. I guess it’s more about what our founders used to call flexibility.

I sometimes wrote things like this:

sub nose {
   my $cuke = shift;
   1 if $cuke;
   return;
}

This should work as well:

sub nose {
   my $cuke = shift;
   1 if $cuke;
   undef;
}

[download]

And i‘m pretty sure that you are aware that return undef; AKA return; isn’t the same as return 0;. But it may be that I even forgot this issue because of lack of practice.
