I have some improvements towards R7RS support after which, if I remember
correctly (it's been a while since I worked on it), most R7RS-small
libraries work just fine in Guile.

    https://github.com/TaylanUB/guile/tree/r7rs-wip

Last I tried to draw attention to my patches, everybody seemed too busy,
but people should feel free to pressure me any time to cooperate in case
there's more I can do.

I think Mark desired a rebase on master, where support for datum labels
could be implemented without dirty hacks or heavy performance cost,
unlike on stable-2.0.  Such a rebase seemed beyond my skills with
Guile's code-base last I checked...
