Strange, never had a problem with this. If I need to reference non-pointer I just use key(append(foo, items[k])) but i find it weird that the print example is not working since in loop the value is passed by copy, just like everywhere else in go, so it should work correctly. as for pointer, again, pass by copy. I see no problem here, it either never bit me in my ass or i figured it out soon in my Go journey.
