A better approach, for the interactive preparser, would be to show all the
routines in all the namespaces, and ask the user which one to use.

For the interpreter (or noninteractive preparser), flag an error, and abort.

As do I. I did mention, that my namespace parser DOES recognize this fact ...
we are in complete agreement on this part, it would seem.
