Disable automatic interning

[George Sakkis]

Is there a way to turn off (either globally or explicitly per
instance) the automatic interning optimization that happens for small
integers and strings (and perhaps other types) ? I tried several
workarounds but nothing worked:

>>> 'x' is 'x'
True
>>> 'x' is 'x'+''
True
>>> 'x' is ''+'x'
True
>>> 'x' is 'x'*1
True
>>> 'x' is str('x')
True
>>> 'x' is str('x')+str('')
True
>>> 'x' is str.__new__(str,'x')
True
