Hmm, I tried that, but it didn't work.

-> ./ruby173/bin/ruby -v
ruby 1.7.3 (2002-12-04) [i386-freebsd4.6]
-> cat p1.rb
def _parse
  loop { puts yield }
end

def parse
  i = 0
  _parse { 
    #(i+=1) == 3 ? rtn = nil : rtn = i
    #rtn
    if (i+=1) == 3
      break nil
    end
    i
  }
end

parse
-> ./ruby173/bin/ruby p1.rb
