Rubinius experiment: generate bytecode for a method call

quux.rb

klass = Object.const_set :Baz, Class.new

method = klass.dynamic_method :main do |generator|
  generator.push_self
  generator.push 42
  generator.allow_private
  generator.send_stack :puts, 1
  generator.ret
end

Baz.new.main

# Error validating bytecode: corrupt instruction sequence

Hi, E.J.

Thanks for this. You can also call send, a helper method whose existence I wasn't aware of when I wrote this Gist, but which Brian Ford pointed out to me:

    generator.send :puts, 1
