Yeah, I guess getting the specification right is more important first.

As for syntax, I guess we could maybe do something like

   boost::find[_f,_e]( rng | filtered );

Then, other return ranges could be specified in this EDSL as

   boost::find[_f+_1,e_]( rng | filtered );
   boost::find[_f-_1,e_]( rng | filtered );
   boost::find[_b,_f+_1]( rng | filtered );
   boost::find[_b,_f]( rng | filtered );
   boost::find[_b,_f+_1]( rng | filtered );

and perhaps even allow

   boost::find[_b+_next(n),_f]( rng | filtered );

etc.
