You can use this T:

return T.stringof;

class Child : Parent {

void main() {
auto p = new Parent;
auto c = new Child;
assert(p.typeName == "Parent");
assert(c.typeName == "Child");
}
Could 'this T' be used for a static constructor ?
-----
class Bar
{
static T construct(this T, A...)(A a)
{
return new T(a);
}
}

doesn't work. And similarly to the the orginal post:
-----
class Bar
{
static typeof(this) construct(A...)(A a)
{
return new typeof(this)(a);
}
}
class Foo: Bar{}
Foo foo= Foo.construct; // fail
----
construct() won't be redefined in the Bar descendants.
