[plt-scheme] Non-syntax-rules macros in scheme/base

The following works:
#lang scheme

---
#lang scheme

(provide test)

(define-syntax test
  (lambda (stx)
    #'2))
---
henk at korhal ~ $ mzscheme -i -t test.ss

> (test)
2
---

However, if I switch the above to use #lang scheme/base, I get the following:

---
henk at korhal ~ $ mzscheme -i -t test.ss
Welcome to MzScheme v4.1 [3m], Copyright (c) 2004-2008 PLT Scheme Inc.
test.ss:6:2: compile: bad syntax; function application is not allowed,
because no #%app syntax transformer is bound in: (lambda (stx) (syntax
2))
---

Is this a bug, or is there something in #lang scheme which I need to
require when using #lang scheme/base?

Thanks,
