| Well, I think that this very well illustrates problems with Axiom:

I must confess, however, that I get very nervous when codes are deleted.
(And I do confess I delete codes too).  It is good you've looked into
that problem.  Edge cases are also part of fixing bugs, so I believe I
feel like Tim on this particular topic.

Could you write up this kind of insight in the pamphlets?  It would be
useful for some of us in the future.
