     * Unfortunately, [symbol] for the `action("")` call will be pointing to the `Function1<P1, R>.invoke(p1: P1): R`, because we
     * intentionally unwrap use-site substitution overrides. Because of this, `symbol.name` will yield `"p1"`, and not `"bar"`.
     *
     * To overcome this problem, [name] property is introduced: it allows to get the intended name of the parameter,
     * with respect to `@ParameterName` annotation.
