Re^4: I don't understand this grep

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...

[gwhite]

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.
