isn't that a feature? I don't think it is a feature. In C++0x mode, if one includes <tuple>, one should get std::tuple. That's what the C++0x working paper says. In any mode, if one includes <tr1/tuple>, one should get std::tr1::tuple. That's what TR1 says (well, TR1 might say that you get std::tr1::tuple from including <tuple>; different vendors have done different things, here). I don't think support for C++0x precludes support for TR1. They coexist very well, especially because TR1 was designed to be compatible with C++0x. For example, C++0x-conforming implementations of the TR1 facilities also meet the requirements of TR1. Ah, I see. Hey Doug. Yes, indeed this is the case: I pointed it out a couple of times already. I'll try to implement this other behavior, but without injecting namespace std::tr1 as part of C++0x items. -benjamin (In reply to comment #2) > I don't think support for C++0x precludes support for TR1.

Hi Doug. Upon Benjamin' invitation, I'm working on this issue, with the initial goal of making progress on the C++0x version of type_traits (for example, it will exploit more front-end builtins). Now, however, I do not agree completely with your statement above: certainly, for example, a C++0x-conforming type_traits doesn't meet the requirements of TR1. That, in turn, sheds doubts to the very point that TR1 facilities must be available in C++0x mode: if the user does an using from namespace tr1 to namespace std of a tr1 facility which finds a same-named, but incompatible facility (i.e., implementing different semantics) in namespace std, which one is supposed to "survive"? Nevermind: that scenerio is illegal anyway, of course. I think I will just try to implement what you suggested on libstdc++ some time ago...
