[RFC] type safe trees

    But this lets you schedule native bootstrapping further down the chain,
    at which point you need to have all languages working _anyway_!  Unless
    "for development" you mean "just C".

Well, you have to start someplace.  And it's harder to first bootstrap
a C++ compiler than a C compiler simply because it's a more complex
language.  You don't get the native compilers until you start porting
them.  The cross-compilers only get you so far.
