Subject: Idiom wanted: do-while

So I was working on the quiz solution, and
I had some code like this:

   b = simulate board,m
   while another_turn?(b,m)
      b = simulate b,m
   end


If I was doing this in C, I'd use a do-while loop instead, to avoid
repeating the line outside the loop:

  b = board;
  do {
    b = simulate(b.m);
  }
  while ( another_turnta(b,m));

What's the do-while idiom in ruby?
I ended up with this, but it needs an extra flag variable:

  b,taketurn  = board,true
  while taketurn
    b = simulate b,m
    taketurn =  another_turn?(b,m)
  end

Is there a ruby idiom for do-while?
