What's wrong with:

assert foo and bar and i > 10, \
  "if foo and bar i must not be greater than 10"

<MHO>
When there's too much hysterical cruft and warts accumulated from the
past, it's time to throw away and clean up, even if it breaks a lot of
things. Trying to keep compatibility at any price would be just suicidal
IMHO - time to get rid of old warts and come back to simplicity. "one
obvious way to do it" rules.
