Dear William,

I think that the "usual sign convention" is a bad idea. 'myatan2(x,y)' should 
return unevaluated, since there is no way of knowing in which quadrant 'x+%i*y' 
is. That's why I proposed 'OrderedRing', in which case the answer is clear. We 
would have to think of the case of members of 'COMPLEX EXPR INT' where we 
happen to know the quadrant.
