[Numpy-discussion] Boolean output for Object arrays with M

Hi Chuck,

O.K.  I've finally caught up with you, I think (at least as far as the 
umath generators go). 

All TD(M,.....)  lines should *not* have out='?'

The reasoning is that this specifies a ufunc type with object inputs and 
boolean array outputs where the function is a method of the object 
input.   However,  the output of a Python method is not going to be a 
C-boolean.  It will be an Object. 

Thus, I think that you are right and removing the out='?' from all 
TD(M,...) lines is the right thing to do.
