Thanks!  That's useful to know; if `quote' is added I can factor out an
implementation-specific reference implementation for that and provide a
portable R6RS implementation of the rest.  (It's also good to know for
my RaList planet package).

Do other Schemes provide ways of defining quote-like forms?
