Details:

R6RS-lib 12.4:
"P is of the form (P1 ... Pk Pe <ellipsis> Pm+1 ... Pn . Px), where
<ellipsis> is the identifier ... and F is a list or improper list of n
elements whose first k elements match P1 through Pk, whose next m - k elements
each match Pe, whose next n - m elements match Pm+1 through Pn, and whose nth
and final cdr matches Px."
So, this
|#
(let-syntax ((m (syntax-rules ()
((_ ?x ... . ?y) (list ?x ... ?y)))))
(write (m '(1 2 3 . 0))))
#|
is legal, but guile produces
ERROR: In procedure macroexpand:
ERROR: syntax-case: misplaced ellipsis in (dummy ?x ... . ?y)
