FSharpFunc + ToString() Analyzer suggestion

[En3Tho]

While I was skimming through our code I found a funny bug: someone wrote Guid.NewGuid.ToString() and forgot to put those "()" after NewGuid call. Can we have an analyzer to find such calls (at least string/ToString) on FSharpFuncs?

Interesting, yeah that could be a good analyzer. More generally, this would probably be:

A method or F# function that accepts unit as input that does not have a unit as the parameter emits a warning at the call site. Then a quick fix would just be to add () at the end.
