"Truly necessary" is never going to be a really objective measure, and hence
is not an easy threshold to meet. Especially talking to someone who could
insist that there was no need for a constant equal to numtochar(13) because
"real programmers wouldn't use it", and that a simple statement, legal in the
syntax, which crashed Rev with 100% reliability shouldn't be marked "critical"
because it could only affect the programmer, who should know better. So I'm
not suggesting any of the following would have got you off the mat. However,
here's a couple of cases:
* Relating to a recent discussion: I'd quite like my IDE extensions to
override "answer" with a version that always had a special 'emergency exit'
control, which would cause it to exit to top in the thread that invoked answer.
'answer'. I'd really like to trap this - currently I can't see any way to do
so. If I could override "answer", I'd have a method.
...but really I'm playing devil's advocate: I'm very happy with the trade-offs
Scott Raney made that give us blazing speed.
