 Member functions `variant()` and `version()` allow checking the variant type of the uuid and, respectively, the version type. These are defined by two strongly typed enums called `uuid_variant` and `uuid_version`.
 
 ```cpp
-uuid id = uuid::from_string("47183823-2574-4bfd-b411-99ed177d3e43");
+uuid id = uuid::from_string("47183823-2574-4bfd-b411-99ed177d3e43").value();
 assert(id.version() == uuid_version::random_number_based);
 assert(id.variant() == uuid_variant::rfc);
