Well, the pages you linked to in your earlier email said GCC supports rvalue references since 4.3 (except *this, but I don't think that's a big deal) [0], while clang has supported them since 2.9 [1]. In fact, the compiler requirements page you linked says that rvalue references (except *this) are unconditionally supported in Frameworks. I guess you were looking for the text "move semantics", but they're essentially the same thing (rvalues are the language feature required to implement move semantics). I mean, I guess there's also standard library support, although we don't care that much about the containers, since we use Qt equivalent. libstdc++ (GNU's implementation) has supported the move and forward helpers since at least GCC 4.6 [3] (that's the earliest version of the libstdc++ manual that's online), and I would be surprised if they weren't in at least GCC 4.4. MSVC has the move and forward helpers in 2010, as I've mentioned [4]. libc++ (LLVM's implementation for Clang) is irritatingly vague about when any particular feature was implemented, but I'd be highly surprised if whatever libc++ shipped with Clang 3.0, let alone 3.1, didn't include move and forward. tl;dr: yes, you can use move semantics. I'll make that more explicit on the wiki page.
