Yes, even I understand that!  Maybe this is the correct use for the prefix "*"
that gets freed up by removing typeglobs ???  "_" would be OK, I suppose, but
could conflict with some programming styles I've seen, with leading "_" in
variable names.

I was waiting to learn more about currying before I raised the issue of repeated
use of placeholders, but that seemed to be missing in this RFC.

Truly a candidate for being called a "whatzitz whatzitz"!
