How to tell an identifier is a module?

[bearophile via Digitalmars-d-learn]

__traits(allMembers, mixin(__MODULE__)) also yields a module name 
like object, but then how can you find out that "object" is a 
module?

This doesn't work:
void main() {
    pragma(msg, is(int == int));
    pragma(msg, is(object == module));
}
