Today it came to my attention that R6RS says in section 12.2 that a syntax object may be "a nonpair, nonvector, nonsymbol value", which counts as an "unwrapped" syntax object. Note that they may not be symbols. http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-13.html#node_sec_12.2 The definition of 'sytnax->datum' just says that it "strips all syntactic information from a syntax object" so I guess it really is a no-op on objects that are not pairs, vectors, or symbols. http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-13.html#node_sec_12.6 Taylan
