What's wrong with just defaulting to $self? That's standard P5 OO,
expected everywhere, and you can rename it if you want in the method
definition (which is a nice place). None of this package-global "use
self ^;" stuff that's both magic-at-a-distance and lexically scoped.
("no self ^;" anyone?)
You can't huffman-code everything to 0 everywhere. $self is 5
characters, well-known, very similar to other languages (like JS,
Java, and C++) and only one of the characters is shifted.
