The old experimental Go maps package was very useful. Infortunately since 1.23 the new stable maps package only returns iterators, so every time you need a slice you have to wrap the call with slices.Collect.
I understand the appeal of iterators for optimization (less intermediary allocations), but I'm not a fan of the growing complexity of the langage (e.g. "func EqualFunc[M1 ~map[K]V1, M2 ~map[K]V2, K comparable, V1, V2 any](m1 M1, m2 M2, eq func(V1, V2) bool) bool", not it's not a joke).
