[Numpy-discussion] ufuncs for structured arrays

All, I've submitted the following pull request for NumPy: https://github.com/numpy/numpy/pull/462 This change allows ufuncs to be registered for structured arrays by using a new API method PyUFunc_RegisterLoopForStructType. For example, a ufunc could be registered to take two arrays of type 'u8,u8,u8' and return an array of type 'u8,u8,u8'. I have a trivial example of this included in my pull request, along with further details of my changes. I suspect there might be a better way to do this, so any suggestions for improvements would be welcome. Thanks, -Jay continuum.io
