There's also the Lisp-Stat ecosystem, if you don't already know about it. Data-frame, array-operations and LLA (Lisp Linear Algebra) cover much of numpy's functionality; at least enough to get significant work done.

FYI -  there appears to be a library called numcl that was written to cover numpy's functionality.

I've yet to try it, but thought I'd pass along the link.

There’s cl-ana, which may be a useful substitute in some cases… or april, possibly.

If you specifically want numpy, it may be possible to have Common Lisp talking to python.

Hi Michael

I am all for it.  But, as I said, I am an academic (and a cat).

Should we (as in "a bunch of common lispers", most of whom with day jobs) want to do something like that, how would you want to proceed?  Note that I have been part of many past failures.

All the best

Marco

IMHO, it'd be easier and effective to band up together and FIRST write a proper API specification and THEN implement it in CL.

I agree.  Here’s the API specification for NumPy: https://numpy.org/doc/stable/reference/index.html#reference

Looks rather intimidating. Less intimidating though, than doing the FFI dance, though.
