I'm not sure I follow the above example.  Can switch be something other
than 1 or 0?  If p is non-zero, switch is set to 1 so we 'do actions'.  If
p is zero then switch *might not* be equal to 1 so we set it to zero.  (If
p is zero and switch is zero, then we are stuck in a loop that keeps
setting switch to zero... that part doesn't make sense.)

But I do follow what you are saying in the example below.  On the other
hand, couldn't you accomplish the same thing by doing something like:

while 1 do
  if p then
    k += 1
  else
    ...do actions
  end if
end while

Am I missing something obvious here?
