until a == b:
    some
    thing

ie. the same as while, except until guarantees at least a single recursion.
this would mean very little change to Python to implement, just a minor
modification on the while handler.

it's not as clear as do (code) until but I don't like ending code blocks
with with control structures... esp. not in Python.
