Review Comment:
   I don't think it means `collection_funcs` is forbidden.
   
   `Concat` works with multiple types, including string, binary and array, so it's not just an array function;
   
   As I mentioned above, it looks like a `collection function` supports collection type (map/array/struct/etc) and some other types.
