One possible stab at it (works on Ubutun, couldn't get it to work on
Windows):

#================================
require 'rubygems'
require 'ruby2ruby'

def serialize_block(&block)
  return nil unless block_given?
  klass = Class.new
  klass.class_eval do
    define_method :serializable, &block
  end
  str = RubyToRuby.translate(klass, :serializable)
  str.sub(/^def \S+\(([^\)]*)\)/, 'lambda { |\1|').sub(/end$/, '}')
end

s = serialize_block do |*args|
  something do
    args.join(', ')
  end
end

puts s
#================================

Outputs:

lambda { |*args|
  something { args.join(", ") }
}

This won't sort out the closure business, but will at least extract the
source code of a Proc.
