Comment (by goldfire):

 I still believe this is a great idea and would welcome a formal proposal
 about this. I also still believe that this is something better done in a
 library for a release or so before we start mucking with something so
 fundamental. There's nothing about this that cannot be done in a library
 (modulo `RebindableSyntax`).
