I think a NEP is a good idea. It would also seem to make sense to consider how the dtype itself can hold/calculate this type of information, since that will be the only way a generic ``info()`` function can get information for a user-defined dtype. Indeed, taking that further, might a method or property on the dtype itself be the cleaner interface? I.e., one would do ``dtype.info().min`` or ``dtype.info.min``.
