This is pretty cool. Are you planning on extending the querying ability at all? I would love to be able to use this like Hoogle, point it at my scala code and query for all methods that take a list and return an int, for example.
Yes, Hoogle is super cool, it would be definitely useful to have something like that.
I wrote in the past tools to manipulate ASTs of several languages but I have never looked in a Scala parser. Can you suggest one?
