That is true. I only brought it up as a comparison with e.g. Nim, which does (claim to) have the ability to interoperate with C++ directly without C-ABI shims. D supposedly has similar capabilities, as does Chicken Scheme.

But yeah, the use case ain't to work with C++ code I've written (if I'm writing it, then my goal is to write as close to zero lines of C++ as possible ;) ), but rather to work with third-party C++ codebases that do not expose a C-compatible API (or do so poorly).
