I'm neither, but my needs are similar, and I really want Numeric to NOT
stop, and just keep going with a NaN, inf or -inf. IMHO, that is the
only intelligent way for an array package to behave, and you get a
performance boost as well!
However, my understanding is that the IEEE special values are not
universally supported by compilers and/or math libraries, so this poses
a problem. I wonder if it's still an issue or if all the compilers of
interest have the requisite support?

Maybe a python wrapper around Blitz++ ? I would love that!
David,
If you could apply your skills to profiling array creation in numarray,
you'd be doing a great service!
