Comment (by Rob Desbois <rob.desbois@…>):

 Actually I was talking rubbish earlier, we /can/ use enable_if in the
 operator because it can wrap any type you pass as the second template
 param. I've wrapped all the return types in question with an enable_if
 using the new struct ptr_container_detail::is_compatible.

 My own tests and those in /libs/ptr_container/test all check out fine,
 error messages are helpful and appear for the offending line of user code.
