Whoops! That's what I get for assuming Racket makes the same mistake that
Python does :)

This is not accurate about default arguments -- they are evaluated
every time. See this example: http://pasterack.org/pastes/65766

Default values for function arguments are computed once when the function is 
defined, not each time the function is called. You'll want to make the defaults 
all false and get the parameter values inside the function body.
