I have a question on make_shared. Consider a class which intends to
force all instances to be handled via a shared_ptr. I used to do this by
putting the ctors into the private section and adding static
create()-methods in the public section. Example:

class X
   X( int, double );

   static shared_ptr<X> create( int i, double d )
      return shared_ptr<X>( new X( i, d ) );

Replacing the returned expression with make_shared<X>( i, d ) wouldn't
work, since it requires a public ctor.

Is there any solution to this or do I have to make a decision between
efficiency and a safe interface for X?

Regards, Daniel
