Yes I am familiar with these excursions. However, my message was directed
entirely towards the C++ community and C++ itself. Other languages have
their own uses and excuses. Boost has Wave and I think it is under-used.
This is my point.

D is indeed interesting. But I wonder how far C++ can be taken with M4/C++
before it breaks.

I think we all wish C++ was something other than it is. Some more than

But what can be done with Boost.Wave to make a C+++?

And, is there any serious effort to make a formal and correct C++
interpreter? It can of course be done. I will argue that it has to be done
sooner than later if C++ is to remain relevant as an actively used (as
opposed to necessarily maintained) language going forward.
