-// In many cases we dont want to do anything if the
-// builtin was given an empty list. This is because
-// allocating memory for a list is costly, so its
-// better to skip if it we can. Furthermore, checking
-// if a list is empty requires both seeing if the list
-// is a NonEmpty layout and if its a List(elem_layout)
-// but with a length of 0.
+// This function checks if the list is empty, and
+// if it is, it returns an empty list, and if not
+// it runs whatever code is passed in under `build_non_empty`
+// This is the avoid allocating memory if the list is empty.
