A number of years ago, someone suggested a "comfrom", to match a
"goto".  When it was first mentioned, it was as a joke.  However, the
more I thought about it, the more it appealed...

The idea is that both ends of the goto are labeled.  This has several
advantages:-
 
(1) At the target label, the "comefrom" clearly identifies the places
from which the current label can be reached, and just how many places.

(2) Also it will help to discourage indiscriminant use of the
"dreaded goto", without preventing its use in "appropiate" contexts.

(3) This would give the compiler more scope for picking up errors.
