The current Ruby 1.9.1 doesn't have the required features to allow ParseTree's runtime features to work - which means some libraries that depend on those features won't work. Examples are Merb's action arguments or heckle. We take a look at the state of ParseTree - and how ruby_parser is a possible way out.
