I looked into https://github.com/qerub/rackjure/blob/master/rackjure/lambda-reader.rkt As far as I understand, reader-proce returns #'(lambda ...) for #λ(...). But, according to http://docs.racket-lang.org/reference/reader-procs.html it should return (datum->syntax #f '(lambda ...)) Maybe, this is the source of the error
