Great stuff!  Thanks!

BTW: my impression was that much of the Numeric C code is
generated by python code generators.  Is this (still) true?  If so, are the
generators available?  Might make a C-implementation of a
scatter-gather (or alternative) C level array easier.

(looking at umathmodule with SBYTE_greater, LONG_greater, ...
it looks suspiciously like an expanded macro...)
