--- Comment #1 from anonymous4 <dfj1esp02 at sneakemail.com> ---
private template enumRep(T, S, S value)
if (is (T == immutable) && isExactSomeString!T && is(S == enum))
{
    static T enumRep = toStr!T(value);
}

If I mark the argument as immutable, then it compiles:
private template enumRep(T, S, immutable S value)

Presumably for enums it should be fine.

Invoking with enumRep!(immutable(T), immutable(S), member) works too.
