I was thinking about comparison operators (<, ==, etc) today and I had
a question. I understand that there is no good way for <, >, etc to
work on matrices because you have to return and integer value. And,
apparently, there is no way to raise an exception here
either. However, it seems like A == B, and A != B are perfectly valid
matrix expressions that should evaluate to true and false respectively
if A and B are the same shape and have equal values. In other words, 
A == B <=> A.shape == B.shape and and.reduce(equal(ravel(A), ravel(B))).

Yes? No?
