Public Instance Methods

explicit?() click to toggle source

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`.

def explicit?
  ![ZERO_ARITY_SUPER_TYPE, SEND_TYPE].include?(@node.type)
