I think it was. Not necessarily that GvR made a list of reasons to
choose C over C++. But the fact that C++ has almost no
interoperability between compilers except via regular C linkage is a
major cultural reason why it's avoided for programs that need
extensible APIs like Python, which is why language implementors try to
The availability of C++ fronts that translate to C isn't the slightest
bit relevant to this.

Well, if you want to write a language that people can write extensions
for using something other than the same C++ compiler you used, then
your only option is to use "C" external linkage which means that
whatever OOP advantages C++ gives you aren't going to be available to
This is true even if you use a C++ front instead of a compiler.
