Sometimes you have to MAKE the mistake to appreciate how/why
to avoid it in future. And you must be prepared to get wrath if
you tell "house prices can't continually rise".
There's a heirarchy of goals:-
- get the D,V list, possibly with help of awk: nearly
- get a better idea if/how awk is useful: partly
- notice how people react if you crit their team: interesting
- the big lesson: superficially simple tools can lead to the same
trap as BASIC..
