is __traits(allMembers) usable in a non-deprecated way?

I just had to change unit-threaded to get it to compile without 
deprecation warnings (and in one case a compiler error). I don't 
know of any approved way of doing it, I just did the first thing 
that worked, which was to check if something was private by:

private template isPrivate(alias module_, string moduleMember) {
     mixin(`import ` ~ fullyQualifiedName!module_ ~ `: ` ~ 
moduleMember ~ `;`);
     static if(__traits(compiles, 
isSomeFunction!(mixin(moduleMember)))) {
         enum isPrivate = false;
     } else {
         enum isPrivate = true;
     }
}


Notice the mixed-in import.
