    http://docs.python.org/ref/comparisons.html

    Formally, if a, b, c, ..., y, z are expressions and opa, opb, ...,
    opy are comparison operators, then a opa b opb c ...y opy z
    is equivalent to a opa b and b opb c and ... y opy z, except
    that each expression is evaluated at most once.
