I discovered that one accidentally.  Initially I used the !~ 
in a solution with s///, where I actually needed a '' to be 
returned so I wouldn't print anything for a match at the end.  
Then I realized it maintained scalar context, and saved me a 
stroke from the $k=~s/.// I was using earlier in the map() 
solution.

The $^H (with literal chr(8)) in my solution was left in by 
mistake.  I would have used a plain 99, except that in my s/// 
solution the number had to be at least 100.  I'm still not 
sure when I can rely on $^H being 256.  I wouldn't have put in 
a gratuitous unprintable character intentionally.
