I don't particularly want to allow map(:anything) :-)  I was just
somewhat surprised to see the idea return in a slightly new form,
since Matz had rejected it a while ago.

If I were designing map(:name), I don't think I'd want it to take
arguments.  But I have no technical grounds for saying so, only
aesthetic ones.
