Totality checking
Example of that is Idris totality checking (http://docs.idris-lang.org/en/latest/tutorial/theorems.html#sect-totality).
This feature could be started as a very specific types of pure functions which could be found to be total for sure and improve it in time. I'm putting a ticket for discussion here, because I didn't find any ticket related to that in GHC Trac.
