i was never really upset about the efficiency issue which has been
changed. i didn't like the semantic problem of throwing away the list
that map is supposed to make. now the docs will say there is no
generated list in void context so that may be harder to argue. but i
still say that map tells the reader a list is being made so look for
it. for modifier doesn't make such a list. someone (possibly abigail)
also pointed out a subtle difference between map and for, map provides
list context and for provides void context to their expression. that can
be worked around IMO.

i just teach that you code to refect your design and not just implement
it. using map in void context is an implementation that generally
doesn't refect your design IMO.

but we should end this thread now. i won't convert any others here and i
won't change my mind on why i don't like it.
