"""Emulate Go's 'defer' statement.

The defer decorator adds the 'defer' function to the wrapped opject
that will push a callable and its arguments to a stack.  The list of
saved calls is executed after the surrounding function returns. Defer
is commonly used to simplify functions that perform various clean-up
actions.
