Well, that won't work if $self->channels returns a list, which seems likely, based on the name.

Update: Need to engage eyeballs before fingers. Thanks massa and jwkrahn for an appropriate whack on the side of the head.

    That should work fine.   What makes you think that it won't work?

    Yes it will work with channels returning a list, according to Conditional operator:
    Scalar or list context propagates downward into the 2nd or 3rd argument, whichever is selected.
    And it won't execute $self->level($level) once for each item of the returned list, which is good.

    Now, the reason why channels is missing is because... well, gwhite didn't show any sub channels { ... } in the module... But he didn't state that it does not exist, either...

      There is not a sub channels { ... } routine, or any list being created when the module is invoked.

      Brain cramp. I could have sworn there was still a $_ in the grep expression. Which would (of course) made your change completely different than the original.

      Ignore me, I need more sleep.
