Haskell sort of has this. You type (_ a b c) and the compiler tells you which methods would make sense there based on all three variables (so in a sense it is even more useful.)

Do you mean you run a build and it tells you in the error message? Or is there an IDE/editor where you could hit a key-combo with the cursor on that line, or near the `_`, and it would show a popup of possibilities for auto-completion?
Yes. Both are alternatives.
