Comment (by RyanGlScott):

 Replying to [comment:4 goldfire]:
 > I ''think'' we'll know that the `k` is not user-written, because it will
 be `Inferred`, not `Specified`.

 So you wish to perform free-floating checks on `TyConBinder`s instead of
 `TyVar`s? That might work... but wait. How would this work for data family
 instances? IIUC, they don't have anything like `TyConBinders`, so I'm not
 sure how we'd perform this check there.
