#9 closed defect (fixed)

tail patterns in syntax-rules

Description

SRFI-46 and R6RS both allow a fixed number of
tail patterns following an ellipsis in a syntax-rules
pattern:

(P1 ... Pk Pe <ellipsis> Pm+1 ... Pn)

R6RS further allows dotted tail patterns

(P1 ... Pk Pe <ellipsis> Pm+1 ... Pn . Px)

where Px only matches a dotted list.

Do we allow either or both of these extensions?
