new haskell project (Was Re: [Haskell-cafe] Subtype polymorphism in Haskell)

[Simon Courtenage]

Hi,

Just to add some details about the project I'm working on in case anyone is
interested.  The project is called Quanthas and is being hosted on
sourceforge at http://sourceforge.net/projects/quanthas/.  The aim of the
project is to produce a Haskell implementation of Quantlib (
http://sourceforge.net/projects/quantlib/)- an open source library for
quantitative finance written in C++.  Haskell is starting to be used
seriously in quantitative finance and risk modelling circles within the
investment banking and finance community, so I thought there would be some
value in producing such a version.

If anyone is interested in helping out, we would be more than happy to hear
from you, since the project has just started and there's a great deal to do
(and learn!).

Best regards

Simon Courtenage
