i agree with your reccomendation, but heres a hack fix...


----wrap.rb----

#!/usr/bin/env ruby

class Module
  def wrap filename
    f = filename.strip
    absolute = (f[0] == File::SEPARATOR or f =~ /^[\w\d]+:/o)
    lines = nil
    errs = ["\n"]
    if absolute
      lines = IO.readlines f
    else #relative
      $:.each do |dir|
	path = File.join dir, f
	File.open (path) {|ios| lines = ios.gets nil } rescue errs << $!
	break if lines
      end
    end
    raise errs.join "\n" unless lines
    lines.gsub! (%r{def\s+(\w+)}o) do |match|
      method = $1
      method =~ %r{^#{self}\.}o ?
	"def #{method}" :
	"def #{self}.#{method}"
    end
    module_eval lines
  end
end

module Timeout
  wrap 'timeout.rb'
end

Timeout::timeout nil do
  puts 'timeout wrapped'
end

module Foo
  wrap 'noexist.rb'
end
