Gauche already have srfi-114 support in the development head but hasn't been released yet;
can you give a rough idea of the new versions (e.g. whether it's a trimmed-down srfi-114 or
has fundamental change), or a timeline?  Not pushing, but would be good to know so that
I'd adjust what to include in the next release.

I have reluctantly concluded that SRFI 114, Comparators, is both too
full-featured and too restrictive.  It needs to be replaced by something
more Schemish, that will not do as much (a lot of SRFI 67 should have
been left there and not brought forward) but will be easier to provide,
easier to test, and better suited to the R7RS-large environment.

Therefore, I am informally deprecating it, and will be replacing it with
a new SRFI which is not yet written.  (There is no formal way to withdraw
or deprecate a SRFI that's already become final.)  As a consequence, the
sample implementations of SRFI 113 and SRFI 125 will also be replaced.
This will not threaten the stability of these SRFIs, because the interface
given by 113 and 125 will remain exactly the same.

Preliminary versions of the new SRFI will appear at
