indeed!

Could I ask what do you mean by static analysis in the context of a completion
library?

David, we've been talking about this during the latest EuroPython, and I've
talked with Laurent yesterday at the Capitole du Libre in Toulouse: IMO we could
start by extracting from lib2to3 "the" parser that could be used by every tools
like ours (refactoring, completion, static analysis...). It would be:
* loss-less (comments, indents...)
* accurate (eg from/to line numbers)
* fast
* version agnostic within a reasonable frame (eg 2.7 -> 3.4?)

I guess almost every one on this list would be interested in such a parser, even
if most would have to do a second pass on the generated tree to get more
"business oriented" tree for their own project. Whatever, we (pylint guys) would
be greatly interested.
