Could this patch be applied to 2.2 branch so that possible 2.2.1 will have the fix also? Using "key in dictionary" format is considered more pythonic than "dictionary.has_key(key)" and on CPython it's also faster (see e.g. [1]). There's thus probably a lot of code using that format and it's a shame that it's so much slower in Jython 2.2.
