The issue that just won't go away. We did it the current way for 
numarray initially and were persuaded to switch to be compatible with 

I agree that it isn't obvious what the number means for complex. That 
ambiguity will always be there. Unless we did a real user test to find 
out, we wouldn't know for sure what future users would most likely 

But in the end, pick one and let's not change it again (or even talk 
about changing it). It doesn't matter that much to me which it is.
