any idea of where I went wrong?

Not really sure either what would cause this reaction to a different LANG env setting. I’d love to be able to nail this down, but .NET/Mono development is beyond me. I might be able to squeeze in checking the code as I’ve been meaning to learn .NET/Mono anyway, but that will happen in a couple of weeks, as I’ve got a deadline to catch.

I forgot to mention that I ran it against mono on Lucid.

As promised, a fresh batch of links to sooth your aching desire for more F#.  I’m particularly excited…
