-LIL uses lists instead of arrays.  The builtin '''append''' command could be used as '''append a $b''', but that would add the entire list in variable '''b''' as one item of variable '''a'''.  The '''foreach''' flattens the items of b for appending to a.  The '''concat''' builtin would end up smushing together the last item of a with the first item of b.
