Here's the quote from PEP 291:

    pybench            Marc-Andre Lemburg          1.5.2         [3]

    [3] pybench lives under the Tools/ directory. Compatibility with
        older Python version is needed in order to be able to compare
        performance between Python versions. New features may still
        be used in new tests, which may then be configured to fail
        gracefully on import by the tool in older Python versions.

If you use new syntax, you'll have to create a new module and then
add it to Setup.py embedded in try-except. If you're just using
new features, then a condition based on sys.version or the specific
feature will do, see e.g. Strings.py.
