Many years ago, in an April issue of Comm. ACM., somebody proposed replacing
GOTO with COMEFROM. COMEFROM was implemented in INTERCAL.
This spoof comes to mind whenever somebody discusses GOTO.
I've decided there's some value in it.
Instead of _replacing_ GOTO by COMEFROM, require all GOTO's to be labelled,
require that they transfer to a labelled COMEFROM, and require that the
COMEFROM refers to the label of the GOTO that goes to the COMEFROM.
The primary objection mentioned in Dijkstra's original letter "GOTO considered
harmful" is the difficulty in discovering how control reaches a certain point
in a program. Coupling GOTO and COMEFROM reduces the severity of that
objection.
