A clarification here: this would be equivalent to IDisposable in C#, but i=
t would not be equivalent to the Context Manager protocol in Python=2E=20

The use cases which motivated them are actually quite different: C# needed=
 a way to handle things like pointers to unmanaged memory, so the design is=
 closely tied to the actual resource object cleaning up its own internal st=
ate=2E Python was looking much more generally at common programming pattern=
s, and a "context manager" can be separate from the resource it is managing=
, or even have no associated resource at all, only "enter" and "exit" behav=
iour=2E
