I ran into the same problem recently...

What about modifying __setattr__ to the following ?

    def __setattr__(self, attr, val):
        fielddict = sb.ndarray.__getattribute__(self,'dtype').fields
        if attr in fielddict.keys():
            return sb.ndarray.__setitem__(self, attr, val)
        try:
            return object.__setattr__(self, attr, val)
        except AttributeError: # Must be a fieldname
            raise AttributeError, "record array has no attribute %s" % attr 

The order is changed, as in Michael's suggestion, but that doesn't set any 
variable in the __dict__, nor does it mask anything. Instead of modifying the 
an attribute, we modify the field directly...
