        The type of the :class:`~BTrees.Interfaces.IReadSequence` is not specified. It could be a list

        All arguments are optional, and may be specified as keyword
        arguments, or by position.

        If a min is specified, then output is constrained to values whose
        keys are greater than or equal to the given min, and, if excludemin
        is specified and true, is further constrained to values whose keys
        are strictly greater than min.  A min value of None is ignored.  If
        min is None or not specified, and excludemin is true, the value
        corresponding to the smallest key is excluded.

        If a max is specified, then output is constrained to values whose
        keys are less than or equal to the given max, and, if excludemax is
        specified and true, is further constrained to values whose keys are
        strictly less than max.  A max value of None is ignored.  If max is
        None or not specified, and excludemax is true, the value
        corresponding to the largest key is excluded.
