For example I have a struct *Item* in my db, and two function *GetAllItem*which return more than one Item and
*GetLastItem* return one lasted Item.
GetAllItem will return a slice of Item and and error if any
So I can return a nil slice if any error occur.
Now is my wonder about GetLastItem:
So I will able to return a nil Item, but it not analog with GetAllItem, so
should I change the GetAllItem to return a slice of *Item?
The Go GC is great, so we can go around and throw garbage everywhere?
Thanks!
