I'm starting to think we should give up on implementing C++ support in 
the language and move it to the library.

eg

mixin(cppFunctionBinding("unsigned long long NameSpace::myFunc(char * 
const && x, long double y)");

expands to some combination of pragma(mangle) and extern(C++)

With the limitation that only declarations can be parsed, it's not that 
bad to implement a ctfe C++ parser, and we can stop the creep of C++ 
features and hack into D.

As a bonus, it could generate wrappers when we really can't match the 
semantics well enough.
