Look - I don't have anything deep to say here. I can only say that between 'records' and 'with-expressions' now in C#, I as a hobbyist F# developer feel like I'm being shaken down by the mafia.
C# designers: "Hey, nice language features you have there. I'll just borrow them for a bit ok, it'll be fine..."
Later, C# programmers: "why would I learn F#, C# does all the same stuff!" (even though it doesn't)
Edit: I admit being both glad that C# is gradually migrating to the ML-style coding which will make F# more mainstream, and nervous that C# will get close enough to kill F# adoption yet too far away to actually get all the benefits of F#.
Some examples of this include the Hindley-Milner type system, partial application, discriminated unions, and all of the compile-time goodness the F# compiler gives and the C# compiler ignores.
