thank you very much for your effort. I think this SRFI was one of the
hardest pieces of work. Even though we do not see the finalization of
any ideas yet, I think the discussion has brought us considerably

As for a new SRFI, I would probably wait until we have some more
syntactic extension facilities in the language. Say, if identifier
syntax is voted into the language (which can likewise apply to
syntax-rules, er-macro-transformer or syntax-case), a new keyword SRFI
(aiming for R7RS-large) will have many more opportunities to shape its
syntax than SRFI 177.

What we could do in the near future is to specify things like
"let-optionals" or "let-keywords" and some other systems like Guile's
as SRFIs. These SRFIs would not necessarily be meant for inclusion in
R7RS-large but they would codify existing practice and can later be
referenced when we start the process for a new unifying keyword SRFI
