This is a wee bit OT, but I am looking for algorithms to implement
search suggestions, similar to Google's Did you mean... ? feature.
Can anyone point me to web pages, journal articles, implementations
(preferably in Python!), or any other resources in this area?
Thanks!

I've searched the standard library docs, and, while there are a couple

I've been looking at PyPy recently, and I see it's reached version 1.0

level of backwards-compatibility one can expect from future versions,
i.e. if I run code on, say, a translated stackless PyPy now, what is
the probability
