Comment (by gridaphobe):

 > What if we add a special `rootCallStack :: CallStack` ...

 I think this is doable.

 One thing worth stressing is that in your scenario the programmer has to
 '''explicitly''' say where they want the call-stack to be cut off (or to
 kill it altogether). This is in stark contrast to the existing scenarios,
 where call-stacks are handled entirely behind the scenes by GHC. But it
 sounds like you really want the option for explicit control, and I kinda
 understand why.
