Ouch, sorry, I do not even have 2.2 installed. Guess with that information,
the whole patch becomes bogus.
On the other hand: simpy reverting pop to get leaves you with the old problem:
you have to drop the check for emptyness of kwargs since legal arguments are
not removed after use. If, on the other hand, you remove this check,
erraneous (p.e. misspelled) arguments are just silently ignored.
Maybe, a wrapper would solve the problem? How would one code a replacement for
pop that works on 2.2 as well? Probably easiest by using get and del within a
try..except block? The wrapper could then have a clear note how to replace it
once 2.3 becomes mandatory sometimes in the future.

Ahh, thanks for your vigilance. I do plan to continue to support 2.2
as long as possible, except for the known issues: datetime and
mathtext. I reverted all the pops to gets. I also made some
enhancements to backend_driver to better work with python2.2 - it now
takes the python to run as a parameter and skips tests where 2.2 is
already known to fail.
Hopefully, I'll remember to be vigilant to test 2.2 before each
