Hi Ilya,

This looks awesome!

I am just curious - since the expected workflow is to always start with ASTMatchers do you plan to provide utilities to overcome limitations of AST you mention?

- Different ASTs for the same syntax
- Same ASTs for the different syntactic constructs

For example - do you plan to implement some functionality for separating a set of AST nodes based on their syntactic nature?
