Tell me about it. What I'd give to have something equivalent for Objective-C (or certain other languages too, e.g. Julia). I'm looking at PyObjC as a stop-gap solution for now, but it sure adds complexity to a project.
Edit: Since SciPy is BSD-licensed and presumably mostly C behind-the-scenes, perhaps there's potential for a group to try and package it up for other languages? I have no idea how large an undertaking like that would be...
