That's merely an advantage to having a C++ compiler. No need to actually use the C++ language. :-)

I don't understand. How can you use a C++ compiler, but not the C++ language? Either a program is required to conform to the C++ syntax (in which case it is a C++ program), or it isn't.

In the specific example of ParseTuple, I don't see a C++ solution without templates, FWIW.

XEmacs has had a policy of compiling without warnings under both C and C++ for about 5 years now, and it catches a lot of stupidity before it leaves the developer's sandbox.

Right. It might be possible to write C++ programs that are also C programs, and it is then possible to release binaries of these through the C compiler. However, in the Python case, I doubt it would gain that much. As the recent const dilemma shows, C99 and C++98 have, unfortunately, different interpretations of "const" (with the C interpretation being more strict).
