Overload on shared_ptr?

template< class A >
void doSomeMethod(const A& a)
{ a.someMethod(); }
template< class A, ... /* remaining shared_ptr template parameters */ ... >
void doSomeMethod(const boost::shared_ptr< A, ... >& a)
{ a->someMethod(); }

template< class A >
void doSomething(const A& a)
{
     doSomeMethod(a);
}
