#11093: Limitations of unique_ptr in C++03 mode

     Type:  Tasks                          |     Status:  new
Milestone:  To Be Determined               |  Component:  move
  Version:  Boost 1.57.0                   |   Severity:  Problem
 Keywords:  unique_ptr, move, emulation    |
-------------------------------------------+------------------------
 This is a follow-up of a thread on boost-dev mailing list which touches
 the topic of boost::movelib::unique_ptr emulation in C++03.

 One of such limitations is related to copy initialization expressions:

 {{{#!cpp
 unique_ptr<Derived> x = make_unique<Derived>();
 unique_ptr<Base> y = move(x);
 }}}

 which won't compile, while:

 {{{#!cpp
 unique_ptr<Derived> x = make_unique<Derived>();
 unique_ptr<Base> y(move(x));
 }}}

 will compile without any problems.

 There are probably some other limitations. It would be best if they were
 documented.
