Respectfully, there is a difference between "It is feasible to compile an executable" and "has industry grade support and tooling". If we discuss just tooling on windows, I heartily concur with the assessment that "F# delivers where other functional languages didn't". I've tried those other languages. I've not yet met anything that would compare with the integration in Visual Studio with the F# command line, project tooling and the .Net ecosystem. Unfortunately I've not tested F# on my Ubuntu boot, but on Windows as functional languages go it is an absolute joy to develop with. Clojure's toolchain comes pretty close, but not quite. For example, FFI to C is much nicer in .Net. Whatever the overall company culture may be, Microsoft actually has lots of bright and well intending software folks working for them, and F# is clearly a labour of love brought to fruition there.
