    """A decorator that traces how a property changes over time.

    In real life, you may find yourself in a situation in which you keep track
    of a variable that changes over time. It may be a path of a moving object
    or (something else; it's late at night and my brain is a bit cloudy so I
    can't give you another brilliant example. I'll fill this in later). As an
    over-simplified example, you may write code to keep adding two to a
    variable in every
    second as follows:

suminb

def f(n):
    def g(m):
        def h(s):
            return m + n + s
        return h    
    return g

a = f(1)(2)
print a
print a(3)
