How is learning to use the compiler correctly a distraction? Is learning
to use a debugger also a distraction? Teaching students to use some kind
of debug mode while developing can save a lot of time (so can enabling
warnings). And it doesn't need to be perfect to be helpful.

AFAIK all implementations provide options to check out-of-bound vector
access. For gcc, it could be -D_GLIBCXX_DEBUG, or the lighter
(the extra define is necessary to catch Amir's example).
