That is only available when the protocol is extended as interface. As example you can not use this way (a method access to the protocol) if you extend the type/class using `extend` or `extend-protocol`. For remove reflection, you should add the appropriate type hint with the `aatree.nodes.INode` interface (generated automatically when you are defining the protocol). If you have plans for using it always as interface (by method access), maybe you should use `definterface` instead. > > Depending on what I try, either I get a class not found compiler error for > file nodes.cli or a runtime error that new-node is NOT a member of the > record that implements INode.
