It's not per se horrible, the problems I see with it are that:

1) it does not warn, it silently eats code in all cases; it should
warn or error if the pragma was inherited via #include.

2) it, or the #include inheriting at least, cannot be disabled from
the command line (even -Wcolumns=32767 wouldn't be a fix).

But yes, if I were still teaching a programming languages class I'd
definitely sneak it in a lecture. :)

Can we add a syntax-check for *.h, just to be on the safe side, maybe?
