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:
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?
