Amen!  That is, while it is indeed easy to construct examples
where Python computes a numerical result only a hundredth as 
fast as the corresponding C code, what I find far more interesting
to discuss are the (surprisingly frequent) cases where Python and
litte languages result in solutions which are *faster* at run-time,
along with being more maintainable and quick to develop.

Yet more chatter on a role for Python with specialized hardware ap-
pears in <URL: http://www.unixreview.com/documents/s=9133/ur0404e/ >.
