Re: [Boost-users] boost and std collisons in c++0x

Good example. But... You have to do something very _special_ if you want to get the same result inside only 'System' namespace. Isn't it? I mean what you can use unqualified ids and usings in most cases without any errors from the compilator _when you use only standard facilities_.

What you can say about following pieces of code: std::vector vec; std::for_each(vec.begin(), vec.end(), std::bind(&std::shared_ptr<SomeClass>::get, std::placeholders::_1, std::bind(&SomeClass::foo, std::placeholders::_1, 10))); and vector vec; for_each(vec.begin(), vec.end(), bind(&shared_ptr<SomeClass>::get, _1, bind(&SomeClass::foo, _1, 10))); from the readness point of view? Assume what I place std and std::placeholders namespace into new namespace ('slib'): slib::vector vec; slib::for_each(vec.begin(), vec.end(), slib::bind(&slib::shared_ptr<SomeClass>::get, slib::_1, slib::bind(&SomeClass::foo, slib::_1, 10))); Is it quite readable or your eyes are seeing only 'slib' and '::'? Is _it_ improving of 'code readness'? And you are offering C++ beginners to use such coding style. It is good style, but I'm absolutely sure what beginners (even with C# or Java experience) say you something ugly and then return to C# or Java. :) -- Best Regards, Sergey mailto:flex_ferrum@artberg.ru
