[plt-scheme] (v4) wildcard not allowed in expression

It works for me though:

#lang scheme

(define-syntax x
 (syntax-rules ()
  ((_ 1 _) 'one)
  ((_ _ 2) 'two)))

(x 1 monkey) ; one
(x monkey 2) ; two

Welcome to DrScheme, version 4.0.0.1-svn16jun2008 [3m].
Language: Module.

  Hi - 

  It seems that in v4 `_` can no longer exist in the expression position for syntax-case, is there a reason for the change? 

  Thanks,
  yc
