Hello all, I have implemented an initial version of PEP 393 -- "Flexible String Representation" as part of my Google Summer of Code project. My patch is hosted as a repository on bitbucket [1] and I created a related issue on the bug tracker [2]. I posted documentation for the current state of the development in the wiki [3].
Current tests show a potential reduction of memory by about 20% and CPU by 50% for a join micro benchmark. Starting a new interpreter still causes 3244 calls to create compatibility Py_UNICODE representations, 263 strings are created using the old API while 62719 are created using the new API. More measurements are on the wiki page [3]. If there is interest, I would like to continue working on the patch with the goal of getting it into Python 3.3. Any and all feedback is welcome.
