Does HPy solve the speed issue for C extensions? I thought it was more of a compatibility layer so that things similar to CFFI could be used automatically. CFFI/PyPy on the other hand was slower for the _decimal extension than CPython. CPython's C-extension speed is actually quite reasonable. The only garbage collected language that achieves the _same_ extension speed that I know of is OCaml (which is quite an achievement). SBCL Lisp, which has a great compiler for pure Lisp, also does not have really fast extensions. Does the Graal VM solve this issue?
