That seems sensible.  Any objections?   It is PyArray_Return that 
changes things from 0-d array's to scalars.  It's all that function has 
every really done....

Notice that this behavior was always in Numeric...

a = Numeric.array(5)
a += 10
type(a)

<type 'int'>

 >>> a = Numeric.array(5)
 >>> type(a) == type(a+a)
False

But...

 >>> a = Numeric.array(5,'f')
 >>> type(a) == type(a+a)
True

So, we've been dealing with these issues (poorly) for a long time....
