Detailed Description

template<typename PtrType_t>
class opt_pointer_wrapper< PtrType_t >

Subclass of opt_wrapper<T> where T is a pointer type, for tracking
success/failure, where:
- a non-NULL value signifies "success", and
- a NULL value signifies "failure",
whilst effectively propagating an opt_problem * describing any failure
back up the call stack.
