C++ started as a C macro preprocessor, designed to work as C in UNIX, and by CFront 2.0 there was already too much compatibility to throw away.

Ts is basically a linter, everything else is JS.

c++ bootstrapping as a transpiler back when it was a 1 man show is hardly where it’s at today. The point about self handling in ts should demonstrate there is more than just strip the types going on

There is the whole fit into the same UNIX compiler toolchain as C, without additional changes to the linker, include files, object and archive files.

Oh like how gnu compiler includes an ada compiler ? Or the C++ name mangling ?

Obviously there a common heritage and the shared ancestor is c.

C++ name mangling was exactly designed to be able to link C++ code with a standard UNIX linker that only knows C.

GNAT has zero compatibility with C source, doesn't even make sense.
