[racket] Problem with case

Hi Joe,

I treat 'cond' as the general, all-purpose conditional branching
thing, and it's my primary tool.  I use the other two if the
conditions I'm testing against fit their shapes.  If I'm pattern
matching against structures, then I use 'match', and if I'm matching
against single pieces of literal data, like characters or symbols,
then I pick up 'case'.


I think 'case' is supposed to have good performance compared to the
other two, due to work by Jon Zeppieri
