Fair enough.

SRFI-47 (which is upward compatible with SRFI-63) is implemented in
SCM, Guile, and SLIB.  So renamed or not, SRFI-63 would lack
interoperability with at least one existing, finalized SRFI.

SCM, Guile, and any Scheme using SLIB have Bawden arrays.  Every
recent Linux distribution includes Guile, so that should count for a

But this pissing contest should be largely irrelevant to R6RS --
SRFI-63 is more capable (uniform arrays), better integrated with R5RS
(specifying vector, string, and EQUAL? behavior), compatible with
SRFI-58 array syntax, and better designed than SRFI-25.
