Duck Typing on Wikipedia

Wikipedia has an entry on Duck Typing, that I intend too clean up. I
am aware that Ruby does duck-typing admirably and would ask the
interested to peruse and
add to the discussion anything they think is relevant prior to the re-
write. (That is the Discussion page or this thread).

I write in Python, (ducks, peers out from behind a tree), but have
been trying to make my explanations generic.

Thanks in advance, Paddy.
