Friends,

Perhaps I have been away from Perl for too long, but the following problem has me baffled. I would like to die or warn depending on a setting. The following does not work: 

if ($error) {
    ($die_on_error ? \&die : \&warn)->($error);
}

This gives me Undefined subroutine &main::die called.... Neither can I successfully reference CORE::die or CORE::GLOBAL::die.

I have two questions:

  1. How do I take a reference to die?
  2. Is there a common Perl idiom to do what I want?

Thanks!

UPDATE: My perl is 5.10.1
