Okay, thanks for the info. (One reason I ask is because qtExtensions¹ actually replaces 'foreach' with either a real range-based for, or - for pre-C++11 compilers - a clever construct that is very nearly equivalent²³.) (¹ https://github.com/kitware/qtextensions, although the public version doesn't have the relevant changes yet.) (² See https://github.com/Kitware/vital/blob/master/vital/vital_foreach.h... qtExtensions QTE_FOREACH omits the BOOST_FOREACH flavor but is otherwise identical. We do require that the compiler supports at least partial C++11, including auto.) (³ I believe the only significant difference from how range-based for is specified is that our version currently requires begin and end to be methods on the container. That's mostly laziness; if it ever becomes an issue, we could try to improve this.) -- Matthew _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
