Note, how Zack cleverly ruled out runtime libraries ;-)

I agree, that more languages mean more complexity, of course.  But IMHO
C++ is just so much more better suited for dealing with data structures,
that this feature nullifies the burden.  OTOH this all remains
theoretical, as long as there's no actual frontend written in C++ (or
whatever else).  If it pops up, we can value if it really adds too much
burden.


Ciao,
Michael.

P.S.: I even thought sometimes about (re)writing some of the optimizations
in C++.  So the stage1 compiler simply would miss some optimizations (as
it still would be translated with just the C compiler), and we would need
a four stage bootstrap.  But as most of the base data structures in the
backend would be needed to remain C, the value of this might be
questionable.
