The [maps] package adds several functions that work with iterators:
- [All](/pkg/maps#All) returns an iterator over key-value pairs from m.
- [Keys](/pkg/maps#Keys) returns an iterator over keys in m.
- [Values](/pkg/maps#Values) returns an iterator over values in m.
- [Insert](/pkg/maps#Insert) adds the key-value pairs from seq to m.
