If I ever teach a class, anybody who tries to abuse Turing completeness
like this will be requird to write his entire treatise on the
blackboard several times as punishment.

Turing's theorem shows, in essence, that a programming language can
implement any algorithm, but that's about it.

If you look at the percentage of a typical program that's devoted
strictly to implementing the fundamental algorithms, you'll quickly
realize that this is FAR from the entire set of capabilities of a real
language.

I should also point out that while C++'s templates are Turing complete,
C's macros are not, so Turing completeness is clearly misplaced as a
consideration here.
