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
