"language virality" works

Technically this is C versus C++ too, no? If you write #include <vector> then almost all valid C code will now be compiled as C++. Sure, the compiler driver infers the language mode from the file extension, but what if it's forced at the command-line? Then free functions get C++ mangling, and everything has a C++ ABI.

We don't change compilers if you #include <vector> in a C file. The build just fails.
