Hello world,

here is my first patch made from the git world.  It certainly took
enough time to work out how to to this, but I think I have it
figured out now...

Anyway, the fix is rather straightforward. We cannot have a reference
on a function. If this slipped through on parsing, let's issue the
error during resolution.

Regression-tested. OK for trunk?

Regards
