Making code 2.1 compatible

Thanks for the reply Mark,

pbf? Is that Guido?  Oh, Google tells me it's the Python Business
Forum.  Ok, so pbf likes 2.2...

I'm happy with 2.2.  However, having 2.1 code in Leo would make Leo a
bit more available to people until everybody changes over.  Maybe
everyone should just convert to 2.2...And Leo for that matter :-)
