Hi everyone,
I am desperately in need of a #lang exact so that decimals are read as
exact values.
I thought this would be extremely simple:
..\exact\lang\reader.rkt
(module reader racket/base
(provide (rename-out (exact-read read)
(exact-read-syntax read-syntax)))
(require (rename-in racket/base (read base:read) (read-syntax
base:read-syntax)))
(define (exact-read . in)
(parameterize ((read-decimal-as-inexact #f))
(apply base:read in)))
(define (exact-read-syntax . in)
(parameterize ((read-decimal-as-inexact #f))
(apply base:read-syntax in))))
;;;;;;;;;;
It installs alright, though chokes on building docs for some reason, but
then when I attempt to use it:
..\exact\lang\reader.rkt:13:6: read-syntax: arity mismatch;
the expected number of arguments does not match the given number
expected: 0 to 2
given: 6
arguments...:
Why is read-syntax getting six arguments?
