	Small caveat: Since whitespaces could occur in an nested
attrbute
	access ("a.  b  .x") , it's better to string them first. An
alternative 
	approach for DotWrapper's __getattr__ could be (not tested):

	def __getattr__(self, attr):
	    bits = map (string.strip, string.split(attr, '.'))
	    return reduce (getattr, bits, self._obj)
