It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

I was tempted to edit your title: "Do rules rule?" But my nose is still bleeding as a result of a limerick. – belisarius


No, but they nowadays let me turn off the lights at night; 24 hours of fluorescence was really starting to make me feral. Brett says I should also mention the tip jar... – Daniel Lichtblau Mar 13 '12 at 20:48

To my interest MatchQ[{1, 2}, {PatternSequence[a_, b_.]}] throws messages but returns True.

Would you object to my closing this as a duplicate of (18393)?

comment Good sources of programming exercises for learning Mathematica programming?
Also look at projecteuler.net -- the higher numbered (more recent) problems are mostly very difficult, but many of the lower numbered ones are approachable.

No, this merely adds the given elements at the beginning and end. Note that the operation must also remove the elements in the case they appear. It is not merely a matter of removing duplicates. Thanks for taking interest however. :-)
