There are plenty more possible.  The opcode language is
probably Turing complete.  Those are the ones you'd expect
to see used solo, though.

I guess for now we should just assume one expression is
fine, but location lists aren't.  If more trouble appears,
we can deal with that (i.e. get it fixed ;-).
