I tend to agree.  I think we've already moved too far in the
direction of writing gcc in GTY-C instead of in C.  (Why this
is a bad thing: the GTY-C language has syntax that isn't
as well documented as the C language, there is only one
GTY-C compiler and it doesn't give great error messages,
and it's harder to do unit testing of a program written in
GTY-C than one written in C.)

If we think we need a language with class hierarchies but
with a C-like syntax, our compiler already supports two
good choices.
