//! bring named enum members into current scope
string flattenNamedEnum(EnumType)()
if (is (EnumType == enum))
{
	string s = "";
	foreach (i, e; __traits(allMembers, EnumType))
	{
		s ~= "alias " ~ EnumType.stringof ~ "." ~ __traits(allMembers,  
EnumType)[i] ~ " " ~ __traits(allMembers, EnumType)[i] ~ ";\n";
	}

	return s;
}

I proposed 'extern(C) enum' to get rid of all those manual aliases but as  
always nothing happened.

Exactly.
