There’s an implicit variable reference by the zero-arity ‘super`:
def some_method(foo) super end
Another case is ‘binding`:
def some_method(foo) do_something(binding) end
In these cases, the variable ‘foo` is not explicitly referenced, but it can be considered used implicitly by the `super` or `binding`.
