digitalmars.D.learn - Documentation wrong. Bug? Old functionality?

This is from the array documentation

enum Color { red, blue, green };
int value[Color.max + 1] = [ Color.blue:6, Color.green:2, Color.red:5 ];

It gives the following errors on dmd 2.052 on windows:

Error: Integer constant expression expected instead of Color.blue
Error: Integer constant expression expected instead of Color.green
Error: Integer constant expression expected instead of Color.red
Error: Integer constant expression expected instead of Color.blue
Error: Integer constant expression expected instead of Color.green
Error: Integer constant expression expected instead of Color.red

Even if I set the enum elements manually the same errors occur. Seems constant
enough for
me though..

The following works
int value[Color.max + 1] = [ 1:6, 2:2, 0:5 ];

Well D has some problems with enums.. You can put those two in module
scope and they will work. I'd also replace the docs' silly RHS style
syntax from this:

int value[Color.max + 1];
to this:
int[Color.max + 1] value;
