   Now that it's too late, I wish it were called
'reversing', after reading the story of somebody who got an
iterator, thinking it was a thing.  Then made a dictionary
out of it twice, and got one good dict and one empty dict.

   'reverse' and 'reversed' remind me of Extended Memory and
Expanded Memory.  One was one, and one the other, but which
was which?
