 ### Stub versioning
 
 You can use checks

+like `if sys.version_info >= (3, 12):` to denote new functionality introduced
 in a given Python version or solve type differences.  When doing so, only use
 two-tuples. Because of this, if a given functionality was

 always put the code for the most recent Python version first.
