+ context variable
+ A variable which can have different values depending on its context.
+ This is similar to Thread-Local Storage in which each execution
+ thread may have a different value for a variable. However, with context
+ variables, there may be several contexts in one execution thread and the
+ main usage for context variables is to keep track of variables in
+ concurrent asynchronous tasks.
+ See :mod:`contextvars`.
