I'm using master branch (till d99fedc5fd38c0), and I found this code
can't run in 2.1, but works in 2.0:
---------------------------------code-------------------------------
(define-syntax define-art
(lambda (x)
(syntax-case x ()
((_ name) (identifier? #'name)
#`(begin
(define name 2)
(define #,(datum->syntax #'name
(symbol-append 'define- (syntax->datum #'name)))
33))))))
----------------------------------end-------------------------------
Of course, the meaning of this code is trivial.

Works for me:

scheme@(guile-user)> (define-syntax define-art
... (lambda (x)
... (syntax-case x ()
... ((_ name) (identifier? #'name)
... #`(begin
... (define name 2)
... (define #,(datum->syntax #'name
... (symbol-append 'define- (syntax->datum #'name)))
... 33))))
... )
... )
scheme@(guile-user)> (define-art foo)
scheme@(guile-user)> foo
$1 = 2
scheme@(guile-user)> define-foo
$2 = 33
Must be some bug that was fixed in the meantime?

Closing bug. Please re-open if you can reproduce it; cheers :)
