A context variable is an object representing a value in the execution context. A new context variable is created by calling the newcontextvar() function. A context variable object has two methods:

* lookup(): returns the value of the variable in the current execution context; * set(): sets the value of the variable in the current execution context. Why "lookup" and not "get" ? Many APIs use "get" and it's functionality is well understood.

Why not the same interface as thread-local storage? This has been the question which bothered me from the beginning of PEP550. I don't understand what inventing a new way of access buys us here.

Python features regular attribute access for years. It's even simpler than method-based access.
