I would say filing an issue might make sense in this case. Here is a related comment from Jonathan: https://github.com/rakudo/rakudo/issues/3222#issuecomment-539915286 – and it explicitly states that $. is a shortcut for method calling. Therefore, use of colon instead of braces should be a valid construct.
