They belong to the [ ] role of Positional. The words function knows nothing whatsoever about this. It belongs to Positional. If you put it inside the parentheses instead of the brackets, it belongs to the Callable, and will be given to words(). Now it is applied as the $limit on how many times to split the string.

But you want words() to have a $selection there instead, so words() can be a list for you instead of letting the list be a list. Why is it so important that words() pretend to be a list, when we have lists that know how to be lists? Why is it so important that you not have to find out what a list is, but instead that words() must pretend that it is a list? Nobody understands why you insist that lists are wired into the functions that produce them and can't possibly know that they can be indexed. And that we must document every function that produces a listas actally itself being a list, including magical $selection parameters, when that is what lists are for. What do you think lists are for, if words() and lines() have to be fake lists to work instead of producing real lists? -- brandon s allbery kf8nh allber...@gmail.com
