Thanks for the reply!
Not sure I understand correctly, though.
interface I {}
class A : I {}
void test(T)(T t) if(is(T: I))
{ writeln(T.type.stringof); }
void main()
{
A.test;
}
throws:
Error: no property 'test' for type 'app.A'
which it of course does... test(A) makes no sense either.
I need to call it statically and want to know the derived class type in
the base class (or interface) function template.
Is there a trick in your answer? : P
Sorry, I didn't read your original post thoroughly, you need an instance
to make this work properly.
A a;
a.test; // should work
What you are looking for is virtual static methods, and D doesn't have
those. I don't know if there's a way to make it work with existing features.
However, your original code has potential as an enhancement request, as
the type is known at compile-time and could certainly be resolved to
pass in as the `this` template parameter.
