"""
A little demo of some of the quirks of Python "closures" with inner functions.

Function closures allow a function to access nonlocal variables in the
enclosing scope, even when invoked outside it's immediate lexical scope.
In languages centered around mutable data types, you would expect to be
able to mutate nonlocals in a closure.

MDN has an excellent rundown of closures, with examples in Javascript.

"""
A demonstration of safe and unsafe ways to write and call Python functions that
take required and optional arguments that are likely to change over time.

Try performing common refactoring operations on the functions such
as adding/removing required/optional args and changing args to and from
required to optional. Also consider combinations of these operations.

The calling patterns marked dangerous are likely to break in some of these
situations, whereas the safe pattern of always calling with keywords
