b has a scalar properties:
The odd issue is that rank>0 arrays keeps their type in similar operations:
>>> a = array((2,), type=Int16)
>>> a + 3
I would expect that rank 0 arrays would behave like scalars with a given numarray type (Int8, UInt64, ...).

or probably more appropriate since it retains the type:
Both not very intuitive, are there any better ways?
