Racket doesn't have anaphoric macros as part of the core language (although there is a module for that), so that's a bit difficult getting used to when coming from Arc, but I find that pattern matching[0] can be used to the same effect:

    (match 123
       ((and (? even?) it) (~a it " is even"))
       (it (~a it " is odd")))
