Such variable names are overly optimized.  They fail to convey meaning.

Generally, it's a bad idea to have two variable names in the same scope that differ only in an inner letter. Letters at the beginning or end should be different. Humans often just don't see the inner letter differences.

It didn't compile :o
I've fixed it in svn.

That's a hoax perpetrated by a chain mail with cherry picked words. Did you ever have trouble figuring "funk" out?

It's not a hoax, we all do it. The longer the word, the easier it is to skip the middle or overlook minor errors. The whole need for a spell checker with undefined symbols is proof of that! Sometimes I resolve those through copy and paste because I don't see a difference.

Just to recap what has been discussed elsewhere, this beta version still has bugs with array appending.

Those bugs have been fixed in trunk and should be incorporated in this release.

Thanks, will do. You're right that this is an absolutely critical bug to fix.

Works on the small experiment, starting trial against the 5.76M files.

Which proves that we don't "ignore" the middle letters, per se; but rather, it is easier to reconstruct them.  Which, of course, means that our brains are willing to play fast and loose with what we see in order to fit what we expect.  And that is the real problem, because Walter saw exactly what he expected to see, rather than failed to see what was actually there.  If Walter were as dumb as a CCD, he would have no problems seeing accurately, but he would then write really crappy code. Can't have it all, I guess.
