yes, you can compare instance of TypeInfo using is or '==' too, 
using typeid which
is returns at run-time the TypeInfo of the argument:

---
void main()
{
     assert(typeid(2) == typeid(1));
     assert(typeid(2) is typeid(1));
     Object a = new Object;
     Object b = new Object;
     assert(typeid(b) is typeid(a));
}
