Extensible records in Haskell

[Keean Schupke]

Just a quick point, which I'm sure you realise, but static typing gives 
you guarantees about the runnability of
a program that dynamic typing breaks... You can do almost anything you 
would want to use dynamic types for
using a sufficently broad algebraic data type. For instance you could 
create a type encompassing all the built
in types and then simply use a list of this type to achieve what you 
need. Obviously the more specialised the type
you use the less cases you have to deal with, and so there is less 
chance of making an error.

    Keean Schupke.
