[Haskell-beginners] Representing most types by the same letter

[Stephen Tetley]

Hi Christopher

This is due to Henning Thielemann - I believe it is an idiom used in
Modula 3, though it hasn't otherwise caught on in Haskell.

If Henning doesn't read this list and reply in due course, you could
try punting the conversation to the Haskell-Art list...
