Copy elision — vazhnaya i neotʺyemlemaya yazykovaya optimizatsiya, kotoraya pozvolyayet nam izbavlyatʹsya ot lishnikh kopirovaniy i peremeshcheniy, chto blagopriyatno skazyvayet·sya na proizvoditelʹnosti prilozheniy. Ni odin razrabotchik ne predstavlyayet sebe kompilyator, kotoryy ne umeyet NRVO. No naskolʹko copy elision deystvitelʹno izbavlyayet nas ot lishnikh konstruirovaniy kopiy obʺyektov? V kakikh sluchayakh on sposoben eto delatʹ, a v kakikh net, i pochemu? A mozhno li chto-to sdelatʹ, chtoby yego uluchshitʹ, i kak eto uluchsheniye povliyayet na proizvoditelʹnostʹ nashikh programm i na napisaniye koda?

Dannyy doklad yavlyayet·sya otvetom na vse eti voprosy i ne tolʹko. Spikery rasskazhut o novom predlozhenii v Standart — ultimate copy elision, i pokazhut, kak on uluchshit zhiznʹ razrabotchikov na C++!
