Creator has those “tags” on the examples page (so that you can e.g. find all the examples that show off certain platforms, or that use QtQuick), so the easiest would be to tag whichever examples we get around to updating to use some c++11 features.

and the ones who are “stuck” will use it as as an excuse not to use Qt, if none of the examples work on their compilers, or they just have mental blocks to understanding them. So we should probably start small.
