That might solve the partitioning problem and solve part of the 
hierarchical problem but won't allow submember access, e.g., 
colors.red.redorange. It seems like a good start though.

I imagine one could potentially build up a set of nested struct 
with immutable members representing the enums:

final immutable struct Colors
{
	final immutable struct Red
	{
		private immutable int _Red = 10000;
		immutable int RedOrange = 10001;
		alias _Red this; // obviously doesn't work
	}

	final immutable struct Green
	{
		immutable int Green = 20000;
	}

}

but with the glitch on the alias(Colors.Red doesn't work)... 
which sort of throws a kink in the solution making more than a 
2-deep nest useless.
