With the move to ast, I've run into all kinds of problems just
to reproduce the old behavior to map if then else's to case.

In additon, I have tried to make it more general so that the
mappping also happens in other cases than only with enum's.
So there may still be issues. If you find a bug, a small
example that can become part of the test suite would
be very welcome.
