Hi!  i was checking out the gem Unroller http://unroller.rubyforge.org/ that
seems pretty promising but I think I couldn't make it work right, I wrote a
simple helloworld program :

require 'rubygems'
require 'unroller'
#Unroller::trace

def outs(n)
  if n == 3
    Unroller::trace do
      helloworld
    end
  else
    yield n
  end
end

def helloworld
  puts "hello world"
end

(1..10).each do |number|
  outs(number) { |x| puts x}
end

I initially tried to trace all the program but it generated many warnings,
still the output for tracking the call to the helloworld method provides
some warnings, here's the output :

1
2
 |    helloworld                                                        |
unroller1.rb:8

 |  \ calling Object::helloworld

Object::helloworld (unroller1.rb:15) (call):
Warning: Expected unroller1.rb:14 =~ /def.*helloworld/, but was:
 |    def helloworld


Object::helloworld (unroller1.rb:16) (line):
Warning: Expected unroller1.rb:14 =~ /def.*helloworld/, but was:
 |  |    puts "hello world y verano"

hello world y verano
 |  / returning from Object::helloworld
4

Am i doing something wrong?

Regards and Thanks
