Some time last year I started the following project, making significant
progress:

https://github.com/taylanub/scheme-srfis

(It's stalled since a while, but I might pick it back up.  Even better
would be more contributors.)

I think it would be great if this became an official part of the SRFI
process.  SRFIs should be implemented as R7RS libraries whenever
possible, and perhaps more importantly, include a test suite!

There is little code by me (mostly it's R7RS-ification of existing
reference implementations) and I would be fine with relicensing all my
code under the SRFI license, and giving the ownership of the project to
the SRFI editors.

What does everyone think?
