Ah yes, the good old "your heuristic doesn't work on my carefully constructed pathological case" observation, wouldn't be the Internet without that.

GP also said "probably". That's how heuristics work.

You would almost think what you described was our profession :-)

Wait, you get paid for Internet snark?

> your heuristic doesn't work on my carefully constructed pathological case

This is a bit like writing unit tests, debugging code, and so on.

It's a heuristic (claims to be probably helpful). You might as well complain that checking string size first as part of an equality check of strings that demonstrably have a very large distribution of sizes is obviously dumb because obviously you can construct same-length strings at will. Breaking rules of thumb is the easiest thing in the world.
