This looks cool for code-driven systems where code has static knowledge of every path in the system. It might be strictly better for things like rendering where types of rendering are code-driven. Like your world can have skybox and such. The examples assuming gamedev 'world' and 'entity' are completely misleading though. Because I think everyone has moved on to data-driven worlds. Think of entity 'advance' from the code examples as an 'entity blueprint execute'.
