A quick note on auto here: The fact that we want to use auto isn't a licence to go crazy with it, instead in the coding style guidelines we will have something like: // Don't use it here auto i = 16; auto j = 16.0; Only use it when you know very well what your're expecting: std::list <unity::component::foo::bar::reallylongnamebaz> bazzes; // Bad std::list <unity::component::foo::bar::reallylongnamebaz>::iterator it = bazzes.begin(); // Good! auto it = bazzes.begin () > > Thoughts, opinions? yay? nay? +1? -1? > -- > Gordon Allott > Canonical Ltd. > 27 Floor, Millbank Tower > London SW1P 4QP > www.canonical.com > > > _______________________________________________ > Mailing list: https://launchpad.net/~ayatana-dev > Post to : [email protected] > Unsubscribe : https://launchpad.net/~ayatana-dev > More help : https://help.launchpad.net/ListHelp > > -- Sam Spilsbury _______________________________________________ Mailing list: https://launchpad.net/~ayatana-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~ayatana-dev More help : https://help.launchpad.net/ListHelp
