I don't think I got what David meant with it either. Assigning instances
of the same type is perfectly valid as long as you do not define some
very peculiar opAssign.
The point here is that person1 and person2 are not instances of the
same type, try compiling the following snippet:
---
struct Human {
string name;
int age;
}
void main() {
Human person1;
typedef Human Mankind;
Mankind person2 = person1;
}

Oh, right, I missed that one, sorry.
This might not be what Hamad wanted to know when he asked »but why
that code works«, but I could think of no other reason why the snipped
he posted should fail to compile.
Yes, the original snippet should compile fine because typedef'd type
isn't actually used in any way except for accessing fields, which of
course have built-in types.
