You not picking on someone?  And, within this
semi-hostile group? ...  OK.  Alex W. is now
complaining about Hugh, but Alex M. isn't.

Well, testing worked for me, and I'm definately
pro-C.  So, I think that disproves that claim.

Rather, it indicates that:
1) failures which can occur do (Murphy's law), or
2) it confirms Knuth's quip on premature optimization.

The use of the word "premature" in this context conveys
extra meaning, alluding to sexual failure, insulting the
technique.  Most people would simply use the word "early".

Personally, I see the failure as the latter case.  If
Hans and others hadn't been attempting to produce the
most compact or fastest representation, they might've
produced something which was easier to verify and safer
to implement, and which is more likely to be correct
even without any testing.

Somehow, we can't seem to escape the "laws" lately...
