FWIW, I was able to make a template to allow me to do what I want:
-------------------
mixin template dequalifyEnumMembers(theEnum, members...)
{
static if ( members.length > 0 )
{
mixin("alias "~theEnum.stringof~"."~members[0]
~" "~members[0]~";");
mixin dequalifyEnumMembers!(theEnum, members[1..$]);
}
}
mixin template dequalifyEnum(theEnum) if (is(theEnum == enum))
{
mixin dequalifyEnumMembers!(theEnum, __traits(allMembers, theEnum));
}
-------------------
Usage:
-------------------
mixin dequalifyEnum!MyEnum;
enum MyEnum
{
Pliers,
Forceps,
Picks,
}
void foo(MyEnum m)
{
final switch(m)
{
// Comment one of these lines out to get the
// "not represented in enum" error.
case Pliers: writeln("Pliers"); break;
case Forceps: writeln("Forceps"); break;
case Picks: writeln("Picks"); break;
}
}
void main()
{
foo(Picks);
}
-------------------
I still can't escape the feeling that this is a hack to work around
limitations of the language or lack of knowledge.
