in thread Function name in a variable, can't recall the concept

Some code that gets a reference to the sub by name. What that code is doesn't matter, though it could be as simple as \&{ $pkg . '::' . $name }.

    nope, this will autovivify a missing function glob $name and return a broken coderef.

    try again.

      You're missing the point. I'm not proposing a solution; I'm saying that yours is ludicrous. It makes absolutely no sense to use 

      my $sub =
   @{ get_array_by_name($pkg, 'ISA') }
      ? get_sub_by_name($pkg, $name)
      : $pkg->can($name);

      instead of 

      my $sub = get_sub_by_name($pkg, $name);

      The implementation of get_sub_by_name isn't relevant to that point.

        it's getting more and more ridiculous, I'm out.

        1) What's wrong with that?

2) You're missing the point. It doesn't matter what the code is, since
+ it's needed no matter what.
