1 ** 0.5 ?

I do like the mathematical cleanliness of making ints and floats do the 
right thing when the answer would be complex, but as a pragmatic decision, 
it might not be the right thing to do. It evidently wasn't thought it was 
when python's current number system was designed. I think Tim Peters has 
an opinion on this.
