   I guess in the case I get `f_name` before `l_name`, I could just return 
exact for both because even though I don't have an index that starts with 
`f_name`, I could hope `l_name` is coming next, and either way since they are 
simple `BinaryExpression`s I could know that they:
   
   1. might be part of an index I have
   2. be able to evaluate them anyway if not
   
   I was just hoping to get a cleaner interface on this that made it easier on 
`TableProvider`s and simultaneously providing the `planner` with info it would 
find useful as we add the ability to work with indexes in the future.
