Need Help??

Nat's suggestion fails to meet my expectations. Mine would be that length should work something like this:

sub length {
  if (1 == @_) {
    return CORE::length(shift);
  }
  else {
    return map {CORE::length($_)} @_;
  }
}

IOW return a list of lengths instead of the number of things in the array. (Which I can easily get anyways.)

Perl can't match both my expectations and princepawn's...

Way ahead of you, length should return a list or a scalar depending on the context in which it was called. A conclusion I came to in Re (tilly) 3: Apparent Inconsistencies in Perl Function Naming...	[reply]
