oh i see now, naming them is just creating a disguise for the base type. then they can become compile-time-known when declared const (see below). only anonymous enum (manifest constant) are true compile time objects. reminds me of my (type)tuple confusion. two completely different animals/concepts, with similar/confusing syntax and blurry docs.


module demo;

import std.stdio;

enum Test{
	test2 = 2,
	test4 = 4
}
enum foo = Test.test2;
const Test bar = Test.test4;	// does the trick
enum wtf = bar;
pragma( msg, foo );		// prints: cast(Test)2
pragma( msg, bar );		// pritns: cast(Test)4

void main(){
	writeln( typeof(foo).stringof, " = ", foo );	// prints: Test = test2
	writeln( typeof(bar).stringof, " = ", bar );	// prints: const(Test) = test4
}
