Help - I'm a C programmer. My code is rarely "cool". I was hoping you could turn this very functional code into something more....I don't know...clever, elegant, cool? I pass a hash table to a function. This function checks the hash out every which way, and could make changes to it in a half dozen different places. The thing is, if a change is made, I have to do it all over again. And again. Until finally no more changes are made to the hash.

I use a global flag. If a change is made in the function, the flag is set to one and I know to repeat the iteration. Here's the code (ignore the %seen, it help me avoid unwanted recursion): 

# Call the Find_First function
while($repeat_flag){
   $repeat_flag = 0;
   %SEEN = ();         # reset hash
   while(($k, $v) = each %GRAMMAR) {
      &Find_First($k, $v);
   }
}

Like I said, this works fine. But can I make it more, well, you know...
Thanks, -tl
