That's how missing components are implemented at the language level:

	> class foo:
	=   def __getitem__(self, s):
	=     return s
	= 
	> x = foo()
	> x[::]
	slice(None, None, None)
	> x[1::2]
	slice(1, None, 2)

The defaults of zero, sys.maxint and one apply to built-in types, but
nothing forces user-defined types to behave this way.

Or maybe I misunderstood your point.
