My go-to projects have varied over time:

1. An implementation of Fisher's exact test for 2x2 tables. This adapts the algorithm from R's fisher.test() function, which was implemented with function closures for optimisation, which does not always map well to other languages.

2. A foreign function interface to the Rmath library. I have now done this for Standard ML (MLton, Poly/ML, Moscow ML, MLkit, SML/NJ, SML# and Manticore), OCaml, Ur/Web, Mercury and MonetDB. Code generation sometimes uses cpp, m4 or the language's tree and string facilities.

3. Discrete event simulation using message passing with an application to cost-effectiveness analysis. Someday, I'll get this published.
