It doesn't work. The compiler parses A<X>() as the constructor of a
template class A, not the template constructor of a class A.
You can write template constructors, but only in cases such as:
class A {
public:
template <class T>
A(const T& t) { ... }
};
void main() {
X x;
shared_ptr<A> a (new A(x));
}
where the <X> is not there and the template specialization is deduced
from the type of the argument.
What were A and X?
Later,
