-// Map is a type-safe equivalent of the standard library's sync.Map.
-//
-// With versions of Go prior to Go 1.20, Map is specified too loosely,
-// as
-//
-// Map[K any, V any]
-//
-// while with Go 1.20 and later, Map is specified as
-//
-// Map[K comparable, V any]
-//
-// This is because with Go versions prior to 1.20, 'comparable' was
-// overly strict, disallowing many types that are valid map-keys (see
-// https://github.com/golang/go/issues/56548). The type used as K in
-// a Map older versions of Go must be a valid map-key type, even
-// though the type specification of Map does not enforce that.
