 Reported by Andy on IRC:

 {{{
 #!scm
 (module foo (bar)
   (import chicken scheme)
   (define-syntax bar
     (er-macro-transformer
       (lambda (e r c)
         `(,(r 'begin)
            (,(r 'define) ,(r 'req) 1)
            (,(r 'display) ,(r 'req))))))))
 }}}

 This gives an error, while at toplevel it's okay.  I think it should just
 print "1", but maybe there's a good reason why it doesn't?

 Also happens with IR macros:
