The whole control flow problem is optional. 
Exceptions can be just another result variant as they
are in functional languages:

  data Maybe a = Just a | Nothing

or

  data File = Handle | NotFound | NotMounted | ....

You get the idea.  Or we can use monads, which from my
primitive understanding seem to equate to a codified
use of these sort of variants.

So perhaps we should be pulling apart the two concepts
entangled in an exception:

1.  Signalling another (abnormal) result
2.  Jumping to code intended to handle that result
