After reading Josh Berkus's email suggesting that the intagg module be dropped, I was wondering what would be required to create a array enumerator (variously called unnest, unroll, array_enum, and, as contemplated by the TODO list, array_to_set). Pavel Stehule's generate_subscripts function provides most of what is needed - however, you need to know the number of dimensions in the array, and it appears we don't have a function to provide that information, at least not in a straightforward fashion. That seems like a pretty useful thing to have anyway, so here's a patch to add it.
I have committed your array_ndims function with the addition of a small regression test, and I changed the return type to integer because that is what the rest of the array functions use for dimension information as well.
