[Numpy-discussion] Do we want scalar casting to behave as it does at the moment?

Maybe this is the source of my confusion... why should scalars be
different from arrays?  They should follow the same rules, as closely
as possible.  If a scalar value would fit in an int16, why not add it
using the rules for an int16 array?

In a strict choice between 1.5-behavior and errors, I'm not sure which
one I would pick.  I don't think either is particularly useful.  Of
course, other members of the community would likely have a different
view, especially those who got used to the 1.5 behavior.
