No argument there, it's certainly possible to write in C++ yet avoid
the various types of binary incompatibility (i.e. don't expose
anything that depends on the STL). It just seems that if we're going
to jump through hoops to do that sort of thing in a C++
implementation, we might consider jumping through a similar number of
hoops to use a language that's a bit less prone to shooting oneself in
the foot.
