Yes, somewhere I have to say how to convert Pat to Exp.

So you mean use a specific (M.Map [Exp] Exp) instead of a general (M.Map
[a] a)? Yes, this would make sense. Then I only translate the value I
want to lookup (if at all) and not the whole map, which I can pass to
the accordant state transformer straight away.
I'll try it out.
