Hello,

I've opened a GitHub issue to discuss the design of HPy's support for calling Python functions -- https://github.com/hpyproject/hpy/issues/122.

Feedback & comments would be most welcome.

TL;DR:

The current proposal is to implement:

HPy HPy_Call(HPyContext ctx, HPy callable, HPy args, HPy kwargs) // inspired by PyObject_Call

and

HPy HPy_CallArray(HPyContext ctx, HPy *args, HPy_ssize_t nargs, const char **kwnames, HPy *kwargs) // inspired by our experience with HPyArg_ParseKeywords and PyObject_VectorcallDict.

Along with HPyCallable_Check and later HPy_CallMethod and HPy_CallMethodArray.

Feedback now will prevent me from having to recode or fix things later (but feedback later is okay too).

Yours sincerely, Simon Cross
