03:00 PM Ruby Feature #21826: Deprecating RubyVM::AbstractSyntaxTree

Note that any usage of `RubyVM::AbstractSyntaxTree` in a gem is, by the documentation of that class and `RubyVM`, invalid (not debugging, prototyping, and research).
That doesn't mean we should break them carelessly, but I think that doe... Eregon (Benoit Daloze)
