I did get some sense of that where F# sort of (actually is) 2nd class to C# which is slowly gaining some F# features, but F# itself isn't well promoted/supported. As for missing language features, they can also be a double-edged sword. I slid down that slippery slope in an earlier venture with Scala. (IIRC mostly implicits and compile times).
