After the "fix", at a first glance the performance seems atrocious, a single call of uuid::base62(): So for example, the base62() method will allocate the string 3 times where just a reference to the static std::string would have been enough. Classes which have a constructor method call this method on each newly-created object, so it is suitable for any initialization that the object may need before it is used.
