You stopped short of giving a working example.
Would you confirm or replace this:

#------------
puts 'ruby %s (%s)' % [RUBY_VERSION, RUBY_RELEASE_DATE]

class Range
  def each_lamb
    each { |x| lambda { |y| return y if yield(y) }.call(x) }
  end

  def each_pnew
    each { |x| Proc.new { |y| return y if yield(y) }.call(x) }
  end
end

(1..4).each_lamb {|ep| p ep; ep == 3}
puts '--'
(1..4).each_pnew {|ep| p ep; ep == 3}
#------------
#-> ruby 1.8.2 (2004-12-25)
#-> 1
#-> 2
#-> 3
#-> 4
#-> --
#-> 1
#-> 2
#-> 3
#------------


Thanks,
