0x? Shouldn't it be 11 by now?
Um, yes, it's just that we have all these 0X macros already and I'd like to be consistent with existing practice, and don't much fancy changing all the existing ones…
Searching for "BOOST_NO_0X" finds about 500 matches in 87 files, almost all in boost/config and libs/config (in fact, most are in libs/config/test).
If people think this is a good idea, and no one else wants to do it, I can do it this weekend.
While looking at this, I noticed that we have two macros: BOOST_NO_0X_HDR_INITIALIZER_LIST and BOOST_NO_INITIALIZER_LISTS
There's an old thread from 2009 where the consensus was that "BOOST_NO_INITIALIZER_LISTS" should be removed in favor of the 0X one.
The only library that is using BOOST_NO_INITIALIZER_LISTS is Boost.Random (and some tests in Boost.Config).
I think I'll make that change first; unless someone complains.
Are these only internal macros? If these are public, it's possible you'll break some user code.
Are we only speaking of macros that indicate whether specific C++11 constructs are available upon inclusion of a given header (that has been added or changed in C++11 relative to C++03)?
Yes, the BOOST_NO_0X macros are C++11 specific (or rather, indicate the absence of C++11 features) As for BOOTS_NO_INITIALIZER_LISTS, people were asking for it to be removed back in 2009: http://boost.2283326.n4.nabble.com/config-Deprecate-remove-BOOST-NO-INITIALI... Daniel James claimed that he was the only one using it, then. Opinions? I don't mind doing the cleanup, but I certainly don't want to do it more than once. -- Marshall Marshall Clow Idio Software <mailto:mclow.lists@gmail.com> A.D. 1517: Martin Luther nails his 95 Theses to the church door and is promptly moderated down to (-1, Flamebait). -- Yu Suzuki
