Description Björn Michaelsen 2013-04-02 10:00:28 UTC
Since C++11 non-member std::begin() and std::end() are available.

It would be nice:
- to have these being able to handle UNO Sequences too
- and then remove ::comphelper::stl_begin / ::comphelper::stl_end and use the std::begin() std::end() instead
Comment 2 Michael Meeks 2013-04-02 14:54:13 UTC
It's worth checking that we can in fact use C++11 in LibreOffice. I currently see zero hits for std::begin() in the code, so this seems a tad risky to me; Bjoern ?

But we cannot rely on them being available in our code base, which still needs to compile with non-C++11 compilers.  And breaking contracts by hacking nonmember begin/end functions into those compilers' std namespaces in order to get rid of comphelper::stl_begin/end is arguably not worth the trouble.

wontfix for now then.
Comment 5 David Tardon 2013-04-03 05:06:01 UTC
We could use boost::begin() and boost::end().
Comment 6 Björn Michaelsen 2013-04-03 11:32:25 UTC
indeed, that gives a nice migration-path to C++11 and is still standard compliant.
Comment 7 Björn Michaelsen 2013-10-04 18:46:36 UTC
adding LibreOffice developer list as CC to unresolved EasyHacks for better visibility.

see e.g. for details
