I so agree it's not even funny.

I've actually started doing it many times.
In particular, i've still got the start of an interprocedural middle-end 
(IE takes trees from many modules) written in C++.

You can't believe how nice it is to just simply be able to do things like 
std::set<tree>, etc.
It seems trivial, but it's really a lot nicer to work with classes.
