Interesting. This demo has not been used very much
from 1993 on, since it has a long-life bug:

	def __cmp__(self, other, *rest):
		#rprt(`self`+'.__cmp__'+`(other, ) + rest`+'\n')
		if type(other) != type(self):
			other = apply(bitvec, (other, ) + rest)
		#expensive solution... recursive binary, with slicing
		length = self._len
		if length == 0 or other._len == 0:
			return cmp(length, other._len)
		if length != other._len:
			min_lenght = min(length, other._len)
				^- here!
			return cmp(self[:min_length], other[:min_length]) or \
				  cmp(self[min_length:], other[min_length:])
		#the lengths are the same now...
