Hello Jay, Cool idea! I like to see work on structured arrays. Just a couple of questions:
- Since there are already have ufuncs for primitive dtypes (int, float, etc), and you are just acting columnwise here, can't you write a single function which interprets the dtypes, gathers the approriate scalar ufuncs, and applies those down each field? Yes registering individual functions using your mechanism will be faster, but it will also be more work. - I didn't try this out myself, but will the normal numpy broadcasting rules apply here?
