Paul, no, I have not tried NumPy (Numerical Extensions To Python).

The only Python (yet to be read) book that I own is Andre Lessa's
"Python Developer's Handbook", 2001, SAMS.

Lessa mentions briefly (p. 15, last paragraph) NumPy and
again later (pp. 364-367).  Lessa shows not a line of NumPy
on those pages, although he gives URL's.  Lessa fails to
mention the connection to J, perhaps for fear of frightening us away.

Calling Java::Python "JPython" further dooms J to anonymity.
I.e., it leads one to think of "J" as implying Java.  Likewise,
the Evil Empire's J++ and J# products.

Kirby is correct about the ability to write really weird looking code in J.
(I assume that is what is meant by "J is maybe the most weird language I know").

Paul, thank you ... NumPy is now on my list of future investigations.

The multidimensional array modules in their various incarnations, Numeric,
Numarray and Numpy - with the Numpy being the latest and hopeful last - are
based on J's array semantics and behaviour.  So in some sense, you can teach
J programming concepts by using Numpy.

Have you you tried Numpy?
