#2481: make_shared and allocate_shared friendship
 Reporter: Michael Marcin <mike.marcin_at_[hidden]> | Owner: pdimov

Milestone: Boost 1.38.0 | Component: smart_ptr
  Version: Boost 1.36.0 | Severity: Problem
 Keywords: |
 It is currently vary difficult to have a class with private constructors
 use make_shared and allocate_shared. This same classes are some ideal
 candidates for private constructors because any class that derives from
 enable_shared_from_this should probably have private constructors to
 prevent misuse. Simplifying friend declarations for these functions would
 be very helpful.

 For example:

 class Foo : public enable_shared_from_this<Foo>
   friend class make_shared_access;

 int main()
   shared_ptr<Foo> foo( make_shared<Foo>() );
