Could you elaborate why `declaresSameEntity` is not enough and we need extra checks for parameter types?
I am asking because if it's not enough for regular functions, maybe there is a similar case for function templates.
And the name is a bit misleading as `F1` and `F2` can clearly be two different functions, so it is unclear what `self`  refers to.
