Instead of verbatim identifiers, how about a special comment giving the Python version in which the file was written?
There could then be a tool similar to 2to3 that converts the file to a more recent version of Python that might have new reserved words. In most cases the new file would merely be a copy of the original, but with an updated Python version.
That would be a serious PITA for modules which have to work with more than one version of Python.
