Changing a closed-over value 1.0 Description

In most languages with closures, it is possible to change a closed-over value and have the change visible in other closures which share a reference to the same variable. Python's syntax makes this impossible.

Putting your changeable values inside a mutable object like a list-- it may occasionally happen that you wish you could change the closed-over values, found in "cell" objects in a function's func_closure tuple.

This script will demonstrate a way to actually change that value, so that functions which also close over that value (share a reference to the same cell) will see the change.
