How to do extern "C" in CPP2?

[jamadagni]

Given that the very spelling of extern "C" doesn't seem to fit within CPP2 syntax, how would one go about programming a C API in CPP2?

#624 mentions a metafunction @c_api but I guess that's only hypothetical?

You can always use mixed mode and mix cpp1 (with extern "C") with cpp2 code.
