What's the D sintax for RTTI? I tried
if(instance.typeinfo === Class.typeinfo) {/*...*/}
but this doesn't work. I tried
if(instance.classinfo === Class.classinfo) {/*...*/}
but this generates an internal error.

How should I write the D equivalent of the following C++ code?

#include <typeinfo>
class Class {} instance;
if(typeid(instance) == typeid(Class)) {/*...*/}

Thanks in advance for helping me! Dario

We discussed it a few weeks ago, but your problem is new.

This is correct and should work.  Could you boil it down to the smallest 
amount of code that can cause the internal error and then post that?

This compiles good but emits a runtime error:
Error: Object 00690D70

All references are initialised to null, so you're dereferencing a null 
pointer there.  Putting a "a = new AAA;" before that line should make it 
work, although you may need to add a constructor.
