| *type* is the type of the expression. In modern versions of Python, this is | ||
| unused. Historically, *type* was used to cast *integer*. |

Can we reformulate this more precisely through a versionchanged? And indicate that the parameter is unused and kept for backward compatibility?

Oh sorry. In this case, I think we can just say that it's not used anymore and only kept for BC. The change has been done in 3.1 so whatever is after 3.1 is already "modern" Python.

| *value*, *larger*, and *smaller* may all be evaluated more than once in the | ||
| expression; consequently, do not pass an expensive operation directly to | ||

Expressions with side effects (ex: value++) should also be avoided.
