Speaking of the Pickaxe, I see that amazon.com is offering used copies for
as little as US$10.70. I guess this is good for Rubyists in general if
bad for Dave & Andy in particular.

Also, Gavin, Matz's "Ruby Language Reference Manual" (a part of your
doc bundle) contains a list of pre-defined variables. Although the
document is a bit out-of-date, it certainly includes a description of $0.
