Re: Subroutines reference from data

in reply to Subroutines reference from data

For most purposes, the UNIVERSAL::can method will serve:

if (my $code = main->can($key)) { &$code() };

If you don't mind turning off strict 'refs', there's the ever-popular defined:

&$key() if defined &$key;

edited: to make the first example strict-safe. Thanks, tinita.

First, Thanks for the quick reply. Gotta love it! Second, Worked excellent. Thanks.

&$key() if main->can($key);

is not strict safe, but:

if (my $sub = main->can($key)) {
  $sub->();
}

also nice (but maybe too obfuscated?) would be (main->can($key)||sub{})->();
