This is a key response. I am more interested in why MSFT would spend more resources creating more languages than on streamlining the facilities for creating languages. Maybe dog-fooding these things over the last 8 years or so has spurred, or will spur product groups and/or MS Research to put as many man-years of work into the meta-tools so that languages can be launched with much less effort. I am impressed, needless to say with F# itself, and I have learned a lot from this thread that I did not know about it, but "what is F#" is not the point of my question.
