Increase maximum number of array dimensions?

See original GitHub issue

At my lab, we’re working with arrays with very many dimensions. We’ve run up against the hardcoded limit of 32 dimensions for np.arrays. What is the rationale for this limit, and is it possible to increase it? Thanks!

Each dimension in my results array is linked to a particular input parameter (whether that is a single value or a range of values).

Have you considered using xarray, which lets you name your dimensions, meaning you do not need to insert padding dimensions of length 1?

I suspect that the original 32 came from 2*32 for 32 bit systems, so 64 might be the proper number for MAX_DIM these days, although actual memory address buses were about 48 bits last time I looked.
