That forces you to name the variable identically to the parameter. For example, you may want to call your variable `loggedInUser` when the fact that the user is logged in is important for the code’s logic, but then you can’t pass it as-is for a field that is only called `user`. Having to name the parameter leads to routinely having to write `foo: blaFoo` because just `blaFoo` wouldn’t match, or else to drop the informative `bla`. That’s part of the tension I was referring to.
