Just a quick explanation for why I'm interested in this...

I've got a two-dimensional array of ints (or bytes, actually), that I
would like to convert to a delimited string (e.g. comma-separated).

This works in Numeric:

>>> from string import letters
>>> alphabet = array(letters)
>>> data = arange(24) # E.g...
>>> data.shape = 6, 4
>>> fields = sum(take(alphabet, data), 1)
>>> ','.join(fields)
'abcd,efgh,ijkl,mnop,qrst,uvwx'
