Guess it could. One other thing we could do is to make enum
namespaces behave like imports.

I'd love to understand "make enum namespaces behave like
imports", but I should probably ask that on D Learn ;=)
When you import from a module, you only need to specify the
module name if there is ambiguity. So for example:
//----
import std.array;
void main()
{
split("hello"); //OK!
}
//----
import std.array;
import std.algorithm;
void main()
{
split("hello"); //Wait... did you want std.algorithm.split,
or std.array.split?
std.array.split("hello"); //OK! That's clearer now.
}
//----
What Andrei is saying is that an enum *could* work the same way:
enum RedBlack //For red black trees
{
Red,
Black,
}
enum BlackWhite //For Checker boards
{
Black,
White,
}
void main()
{
writeln(Red); //OK! No problem!
writeln(Black); //I'm sorry... that's ambiguous :/
writeln(RedBlack.Black); //OK! That's clearer now!
}
Whether or not it *should*, I don't know. "Why not?" I like to
say :)
