It is a known problem. The workaround is to use is(typeof()):

void main() {
     foreach (mem; __traits(allMembers, Foo))
     {
         static if (is(typeof(
             __traits(getMember, Foo.init, mem)
         )))
         {
             enum prot = __traits(getProtection,
                             __traits(getMember, Foo.init, mem));
             static if (prot == "public") {
                 pragma(msg, mem);
             }
         }
     }
}
