  module SexpAnalysis
    # This is the base module for all annotations that can run on ASTs.
    # It includes all other annotation modules to provide all the
    # annotations to the Sexp class. These annotations are run at initialize
    # time for the Sexps and have access to a node and all of its child nodes,
    # all of which have been annotated. Synthesized attributes are fair game,
    # and adding inherited attributes to subnodes is also fair game.
    #
    # All annotations add O(V) to the parser runtime.
    #
    # This module also provides some helper methods to inject functionality into
    # the Sexp class. Since that's what an annotation is, I don't consider
    # this bad form!
