It's under WG1 ballot, and I think if it doesn't make WG1, it will
very likely make WG2.  There are several variants available besides the
SRFI itself.

It's easy to implement parameters portably in a non-threaded
system, so the proposals are about how mutation (as
opposed to rebinding, which is per-thread) interacts with
threads.  http://trac.sacrideo.us/wg/wiki/ParametersSnellPym
defines parameters as thread-safe under mutation, whereas
http://trac.sacrideo.us/wg/wiki/ImmutableParametersCowan excludes
mutation.
