null()/nil() are actually redundant and only contribute thread safety problems. The default constructor already creates a NULL UUID, as it should.
I agree that they are redundant. I am not pushing them, but just wondering why they would contribute to thread safety problems since they return a constant object?
Because of the local static variable.
Ah! Multiple threads may try to initialize the variable at the same time. If it could be initialized correctly, there wouldn't be a problem. Thanks. Andy.
