Not necessarily. That may not happen in the general case. This gets complex. In this particular regex, I think you are right, the first undef results in subsequent undef's. In any event the code I showed will show what happens. As a response I tried to show a method to debug this. The "here is how to grow wheat" instead of "here is some wheat" idea. I'm hoping that it helped.
