We were thinking about not gumming it up further, but un-gumming it is
worth considering too.

That was the reason given by the most strong opponent, if not the only
opponent, when a proposal was made to use the name recur for the construct
instead of overloading let.

I've become used to name let over the past 20+ years, so I'm not sure
whether I'd vote for a change at this point.  I'm interested in hearing
what other people think, however.
