Not really, believe me. Although there are parts of portage that should 
probably be written in c / c++ those are only a small part of all code.

The big problem (if you had looked into it) is that currently the only 
reliable way to read an ebuild is to invoke bash with the whole bagage 
of /usr/sbin/ This is why I am so much against dynamic behaviour on 
the global level. It one breaks the cache, but also makes creating a parser 
(Currently ebuilds are not parsed by portage!!) so much harder.
