I'm not sure if it helps in your case, but you can easily turn off the
optimization by subclassing from the string type:
>>> class mystr(str):
... pass
...
>>> s = mystr('x')
>>> s
'x'
>>> s is 'x'
False
Since mystr can have additional functionality on top of str, the
caching doesn't apply to the subclass instances.
