Btw I think that's a dynamic cast, unless the compiler can optimize it
(I mean it should since it's a template function r

You need a dynamic cast at the call site:
Sub x = cast(Sub)(new Sub()).doStuff();
x will be null if doStuff

Sorry guys this question is entirely wrong. That syntax *is* legal. I
don't know what happened last night when it failed to compile, maybe
it was template-related. Nuke the question.
C/C++ sometimes uses a declaration such as 'cost void*', which is a
pointer to const void. D doesn't have an equivalent to this, since
using const(void)* is illegal.
The problem is if there are two overloads in a C++ class such as this:
foo( const void* ) // equivalent to const(void)*, illegal i

Why not pass it as a runtime argument?
void run(Fun, T...)(Fun fun, T args)
{
writeln(typeid(ParameterTypeTuple!(fun)));
fun(args);
}
void test()
{
auto a = new A;
run(&a.fun, 10);
}

Right, this would only work for templated functions, but maybe not
worth adding then.

Honestly it would be much better if the file a

How will that do the trick if you don't have the reference to the
invoking module?

We could really use __MODULE__ then. I think it's been asked before
but I didn't see any enhancement request in buzilla.
__FILE__?
