Accelerate

For those wondering what it's for: it's basically NumPy + a JIT compiler with standard Haskell syntax (you mostly just need to change the type signatures, not the code).

It can vectorize, parallelize on the CPU, or offload to the GPU automatically.

It's a very mature project, maybe 10+ years old.

If the weird syntax of APL and J bothers you, you can use the familiar Haskell syntax!

Jokes aside, types should help a lot.

I guess the author is unaware of Accelerate.framework, the vector library that has shipped with Mac OS since Jaguar.

What’s the main use case for this?

aren't there like dozens of similar things with pretty much the same name?
