If you need to be able to easily construct indexing objects, create a
helper like:

	> class Slicer(object):
	=     def __getitem__(self, s):
	=         return s
	= 
	> s_ = Slicer()
	> s_[1,2,3]
	(1, 2, 3)
	> s_[:]
	slice(None, None, None)
	> s_[1:2:3,4:5:6]
	(slice(1, 2, 3), slice(4, 5, 6))
	> s_[...]
	Ellipsis
