This is probably too little  to justify the compatibility breakage, but is
there a motive for the "slice" type to be on built-ins ?
(besides people forgot it there at PEP-3000 time?)

It is normally used in super-specialized cases, mostly when one is
implementing a Sequence type, and even there just for type-checking,
not to create new slice objects.


It does get called sometimes in numerical code to construct complex
indexing operations.
