F# is not like Ruby/Python at ALL. F# is statically typed for one, variables are by default immutable, let me give you an example, tell me what you think the following prints? let somefunc() = let i = 10 i = 11 printfn "%s" (somefunc().ToString()) it prints "false", not 11. F# is a lot like ocaml, which it was syntax compatible with for many years. Most developers in the non-web sphere are dealing with multi-core and async issues. F# solves these problems very elegantly.
