For example, what if the constructor body was in another translation unit? By contrast, the return value rule simply has to check the symbol tables to determine whether or not the identifier after the return keyword denotes an automatic object. You can also pass parameter by value. For move-...

But we have to be careful also while using this keyword. for eg : int var =0; decltype(var) and decltype((var)) is diferent; first one deduces to int and second one deduces to int&. so if you are writing a function with return type decltype(auto) and you are returning a ...
