Python 2 can intern 'str' (bytes) strings (with the eponymous builtin,

Has it been moved, or is interning as a concept deprecated?
The former, into `sys`:
http://docs.python.org/dev/library/sys.html#sys.intern
Search the "What's New"s in the future.

I think that the devs decided that interning is a minor internal
optimization that users generally should not fiddle with (especially how
that so much is done automatically anyway*), while having it a builtin
made it look like something they should pay attention to.
*I am not sure but what hashes for strings either are or in 3.3 will
always be cached.
