Code review comment for lp:~therve/storm/binary-and

As an example of the python precedence problem, consider the following:

    >>> (1 | 6) & 4
    4

    >>> from storm.expr import compile_python, BitwiseAnd, BitwiseOr
    >>> expr = BitwiseAnd(BitwiseOr(1, 6), 4)
    >>> compile_python(expr)
    '1|6&3'
    >>> eval(compile_python(expr))
    5
