That is not exactly a bug, but it is an unclarity in the design.

The match* condition fails, but since it is a non-exit clause, that
failure doesn't affect anything -- it goes ahead an executes the next
clause.  Arguably it is doing exactly what your code said.

But it raises the question of what a non-exit match* clause should do
when it does not match.  What do you think it should do?

The idea that occurs to me is this: bind all those variables,
initializing by matching those that can match, and initializing the
rest to nil.
