Good thinking. Makes me wish C were a better language, though ;-)

I wonder if making this a switch() statement is easier to read in
the longer run. The only thing at this point we are gaining by "not
only mapping and enum must match, the orders matter" is so that this
codepath can do the same thing for PICK and REVERT, but these two
would become more and more minority as we learn more words.
