Dictionary, integer compression

[dineshv]

Yes, "integer compression" as in Unary, Golomb, and there are a few
other schemes.

It is known that for large (integer) data sets, encoding and decoding
the integers will save space (memory and/or storage) and doesn't
impact performance.

As the Python dictionary is a built-in (and an important data
structure), I wondered if the Python internals used integer
compression for the dictionary (especially as the size of the
dictionary grew)?
