[Haskell-cafe] Haskell Pangolins

[Dominic Fox]

Hi all,

This is just a request for comment - I've written a short Haskell program,
intended to demonstrate some of the basic features of the language (how to
create a data structure, transform it, and run a user interaction loop). I
would like to know if there are any obvious respects in which this program
could be simplified, clarified or made more idiomatic.

The code may be found here: http://codepoetics.com/code/pangolin.hs

thanks,
Dominic
