 From the "ruby user guide"

 ------------------------------------------------------------
 With `retry', one can define an iterator which works the same as `while',
 but it's not practical due to slowness.

 ruby> def WHILE(cond)
 ruby|   return if not cond
 ruby|   yield
 ruby|   retry
 ruby| end
 nil
 ruby> i=0; WHILE(i<3) { print i; i+=1 }
 012nil
