... 10 to 30 times more slowly under Mono, according to your posting here:


Do Microsoft produce a free (as in speech) .Net framework with
equivalent performance which runs under Linux?  Will they continue to
make F# work with Mono?  or indeed do they support it right now?

The license, "Microsoft Research Shared Source License Agreement"
(http://research.microsoft.com/fsharp/fsharp-license.txt) explicitly
prevents commercial redistribution of the F# sources, and that means
for example that it could never be part of a free operating system
like Debian or Fedora.

In practical, day to day terms I'd better hope that Microsoft Research
continue to produce and support new versions of F#.  If one day they
just abandoned it, or if they decided to drop support of Mono then I'd
be up a creek without a paddle (but with a lot of software which I'd
have to rewrite in another language).

So F# was a separate implementation?  I thought it was derived from an
older version of OCaml - but with the licensing issues above I'm not
about to download the source to check that.

Discussion moved to caml-list.  It's important to get any
misunderstandings about F# resolved.
