Thanks for your in-depth reply. I'm still relatively new to the area
and started off through books that are intended for academic courses.
Augmenting the grammar / features does in fact lead you to situations
not addressed by the same books (although most of the questions can be
answered in the dragon book ...). Still, this mailing list archive has
been a great resource so far in looking for answers and leads.
