     writeln("Typeof T is: ", typeof(t));

This doesn't work, but you get the idea.

typeof(t).stringof

writeln("Typeof T is: ", typeid(typeof(t)));

(Try alternatives of that with a dynamic type, like a class).

     class A { }
     class B : A { }
     class C : B { }
     A a;
     B b;
     C c;
     A ac = new C;

Typeof ac is: A

So it's the variable, not its current contents. Kinda makes sense.

 This doesn't work, but you get the idea.

For a class or interface:
writeln("Typeof T is: ", t.classinfo.name);

 For a class or interface:
 writeln("Typeof T is: ", t.classinfo.name);


     A a;
     B b;
     C c;
     A ac = new C;

     writeln("Typeof T is: ", ac.classinfo.name);

and the result is:

Typeof T is: C

so it really works!!!

Thaks, guys!!
