I added the "string aliases" but didn't create new Python object 
bindings.  So you can currently say something like

    arange(10, dtype='float32')

but cannot yet say:

    arange(10, dtype=float32)

Good catch.   I'll add those soon.

I think scipy_core is intended to add the best numarray-like features to 
Numeric.

When scipy_core matures enough to replace numarray,  numarray will be 
phased out.    If you rely on numarray,  it is definitely worth your 
time to keep an eye on scipy_core and switch when it meets your needs 
better.
