Since this is my first post in this current thread, you either meant 
someone else or are remembering my posts about in- and out-of-band error 
signaling from the last time we discussed this.

One point of the 3.0 cleanup is to remove or change things that we 
definitely would not do today.  When I learned Python, both the find/match 
duplication and the in-band same-type Unix/Cism -1 return stuck out to me 
like sore thumbs.  So I would either

1. just remove find() and leave match(); or
2. change find()'s error return to None, and remove index();

 or possibly consider Josiah's idea of
3. remove both in favor of an index generator.

I am strongly -1 on leaving both as are.
