On: Calling Rust from Cursed Go

> For performance, Go using CGO is going to be closer to Python than Go.

That has not been my experience at all. While there’s still some overhead, recent versions have cgo per-call overhead under 50ns. Python is still nowhere near close especially with multiple threads being used.

Indeed until the Python community embraces state of the art JIT compilers on the reference implementation, this is definitely not the case.

Yes, even with PyPy's heroic efforts.
