-{- Note [Ctx splitting in a recursive pass]
-When writing a recursive pass that processes the whole program, you must be
-a bit cautious when using a Ctx split. The context split may traverse
-part of the program, which will _also_ be traversed by the main recursive
-traversal. This can lead to quadratic runtime.
-
-This is usually okay for something like 'splitApplication', since it is
-quadratic in the longest application in the program, which is usually not
-significantly long.
