hmm, interesting idea, let me mull this one over.

yeah, at some point in my coding life I realized you either
have three choices: 1) huffman-encode variable names; 2)
artificially break at 80 chars; or 3) pretend everyone's
terminal is infinitely wide.  #3 seems to have the least
negative consequences, but most people still choose #1 or #2.

if you pick #1, anyone who reads your code has to either
find your dictionary in the comments or discover it with
archaeology because there are no comments.

if you pick #2 you will always violently offend at least
one person's coding standards and they will reformat all
your code at the first opportunity.

if you pick #3 you can usually have more self-explanatory
code and still stay within 160 characteres *most* of the
time.  with current displays and editors it doesn't seem
too demanding.
