ARGH
check-equal? is actual, expected; not expected, actual. :(
I give up. How the fuck are you supposed to run scripts in racket and
require something else. All I want is the ruby equivalent of:

`ruby -I. -rextras ch03/ch03.rkt`

Is that so hard?

For now, I'm going to do a direct require with a relative path and
hope to god all goes well. Only having one path as a racket argument
seems to work better. Silent failure SUCKS.
