[rules-dev] Miss Manners

[Steve Núñez]

Mark,

Agreed that Manners needs improvement. In it's current form, it's nearly
useless as a comparative benchmark. You might want to check with Charles
Young, if he's not on the list, who did a very through analysis of Manners a
while back and may have some ideas.

Whilst on the topic, I am interested in any other benchmarking ideas that
folks may have. We're in the process of putting together (hopefully)
comprehensive set of benchmarks for performance testing.

Cheers,
    - Steve
