Some observations and questions:


   1. In the RFC, the top example claims to make use of the file()
   function, but in fact does not.  Did you mean fopen()?  Or did you mean
   that this to be an example of someone writing their own file() function in
   PHP for some reason (the "userland" reference is a bit confusing IMHO given
   the context).
   2. In what way(s) do you believe this approach would differ from inline
   functions and what advantage(s) do you see in those differences?
   3. What release version do you believe should be targetted for this?
