when i was using R a few years ago, a number of the packages i was most fond of were themselves at least partially implemented in C++ / Fortran.
e.g.
`gbm` is pretty much a C++ project.
`randomForest` now appears to contain a fair bit of R code, but it still has the (original?) fortran routines for tree construction, as well as C code wrapping the fortran.

My comment was really addressing "it won't be hard to solve in Clojure.". Some things are just hard to get right, period.
