Subject: Redefine while

Hi, is there an easy way to redefine 'while'. I have a class that uses a
while loop. In my unit test it always evaluates to false (which is
correct). I only want the loop to run once, and the enter. Just like an
if.

This is the code I've tried:


def while(condition)
  p "redefined while!"
  yield if condition
end

while true do
  p "hello"
  sleep 1
end


But it loops eternally.
Any help?
