When creating templates, it is sometimes handy to print the type of something. Is there a trivial way to print it?

    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).

Thanks!!!


    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.

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!!
