[boost] unique_ptr, was: Composing non copyable and movable classes

Michael Marcin:

Speaking of unique_ptr is it possible to get a C++03 emulation of unique_ptr into boost?

I've been using http://home.twcny.rr.com/hinnant/cpp_extensions/unique_ptr_03.html for months and it seems to work fine.

To get it into Boost, someone needs to contribute the tests and documentation and commit to maintaining it. :-) That said, I'm not fond of this property of the cited implementation: # This implementation will mistakenly move from const lvalues. const unique_ptr<int> cp; unique_ptr<int> p(cp); // should not compile -- Peter Dimov http://www.pdplayer.com
