When the pedagogical device become the goal in itself, as is the case
with two-column proofs and a few other arcane topics, it's the school
equivalent of going 90 mph in 1st gear--you might pull it off once
and for a short period of time, but you will burn the transmission
and the engine.
Wayne channelling for Barry Simon is certainly asserting something
quite different from what you describe--just look at his complaint
against Lou Talman.
