I'd love to drop Python and go all in with a true array language (i.e. not Matlab), but you only really have 4 options:

Dyalog APL, J, Kdb+, Shakti.

All of those are closed source and expensive (Dyalog is fairly affordable, but still a paid product) with the exception of J. J is a cool language, but isn't quite my cup of tea.

So if one of the new projects ever picked up steam and got a decent sized community with hooks into all the same numeric libraries as Numpy, and some decent charting libraries...then we would have something nice.

You have Kona, ngn/k and others are shaping up. Not yet production quality, but Shakti isn’t there yet either.

I thought Kona was intentionally not going to ever get close to the commercial K languages due to fear of lawsuit. It is supposed to stay a toy.

J is not closed source and hasn't been for a while. https://github.com/jsoftware/jsource

I said "with the exception of J" which was supposed to apply to mean not closed source and not requiring a commercial license (well... outside of Jd).
