I'm trying to understand it, but am getting lost in a maze of twisty little
ampersands, all alike...

This is where I start to lose it:

  s&&!msfQ!&&s&$

I thought the first 's&&' was using the '&' as a regex (substitution)
boundary marker, which would mean "substitute nothing with '!msfQ!'"...
but if so then I can't understand the bit immediately after, ie. '&s'...

...and I'm now thinking "isn't '&&' supposed to be a logical and, much like
in C?"

Dammit.

I can certainly say it uses the ampersand character very effectively. :)
