That was my initial thought when I saw this but thee is one
caveat. The original design creates a single instance of a
scene and returns that on each access. The suggestion above
creates a new instance on every call. So if it is important
to use the same instance each time then the map is a
better solution.
(Although you could instead create a class variable holding
the first instance of itself then use a class constructor
to either create the instance or access the class variable...)
