I agree. In fact, I'd rather see NumPy scalars move towards Python  
scalars rather than towards NumPy arrays in behaviour. In particular,  
their nasty habit of coercing everything they are combined with into  
arrays is still my #1 source of compatibility problems with porting  
code from Numeric to NumPy. I end up converting NumPy scalars to  
Python scalars explicitly in lots of places.
