Comment(by watson1978@…):

 Hmm, it looks like Bugs have mixed into Ripper.

 {{{
 require 'ripper'

 class Parser < Ripper::SexpBuilder
   ms = Ripper::SexpBuilder.new('').methods
   defs = ms.map { |s| s.to_s }
     .select { |s| s.start_with?('on_') }
     .map { |s| %Q{
   def #{s}(*args)
     print '#{s}: '
     p args
   end
     }}.join
   eval(defs)
 end

 def parse(src)
   puts "****" + src.inspect + "****"
   Parser.new(src).parse
 end

 parse "def test(a,b)"
 }}}

 {{{
 $ macruby_select 0.10 t.rb
