Map could not derive from Collection, but yet it can define a method to
return a Collection of Entries:

public Collection<Map.Entries<K, V>> get_entries ();

I propose that we define a special container Entries, with special
properties "key" and "value", and not that we reuse Pair which would
have some generically-named properties "e1" and "e2" (or element1,
element2).

Best regards, Didier.
