Temporary objects are destroyed ad the scope end, not statement end.

is same as:
       auto tmp = f(i); writefln(tmp.ptr);
       // tmp is destroyed at the end of foreach, so prints same address

>   writeln(f(0).ptr);
>   writeln(f(1).ptr);

are same as:
       auto tmp1 = f(i); writefln(tmp1.ptr);
       auto tmp2 = f(i); writefln(tmp2.ptr);
       // each temporaries has own memory, so prints different address
