As a proof-of-concept and as a first attempt to learn F#, I have now also implemented the HS071 example in F#. The F# source code can be found here. This is my first F# program ever, so I am sure it can be substantially improved. Nonetheless, it did compile and efficiently solved the HS071 example. Needless to say, I am pleased to have reached this far :-)
I have not yet packaged the F# example in a regular csipopt release, but the latest revision of the source code can be downloaded via a Subversion client. For further instructions, see this page.
