Do you mean regarding releases (as you say more on below)? Or/also
the mailing list dynamic/responsiveness? Anything else?

R6RS specifies libraries, which are similar to modules. (But probably
much cleverer for separate compilation, and vastly more complicated in
their semantics.)

I've used Guile for a substantial project at work, and I use it for
various little things on my free software machines. But it's true
that I don't have anything to compete for size/complexity with
Lilypond.

For me, almost all of my time since becoming a maintainer has been
absorbed by working on bug fixes, largely to do with slightly odd
platforms (e.g. Mac) or architectures (e.g. ia64). IMO it was
worthwhile to focus on such bug reports soon after they were reported,
because (i) the reporters are still around and interested enough to be
able to provide more info and test fixes, (ii) I believe that running
on more platforms will be good for the Guile community, and for Guile
applications.
Nevertheless, I have also had a rough plan in mind, which I've never
communicated before, except vaguely to Ludovic. I believe Ludovic
disagrees with this plan, so it certainly isn't official. It's just
what I'm thinking, and so might be part of what eventually happens.
Basically, my feeling is that Guile users have been badly burned by
major release incompatibilities in the past, and I really don't want
that to happen again. Therefore my "straw man" plan is that
- we stay on 1.8.x for a while
- we treat "master" as a pot of goodies, which we aim incrementally to
merge across and release as part of the 1.8.x series
- in effect, therefore, we will be releasing one (or a small number
of) new feature(s) at a time - which I hope will give us the
time/space to consider and document any incompatible issues that there
may be
- we don't do a big jump to 1.10.x, by just deciding to do so at some
time (+ a bit of pretesting), because I don't feel confident that we
can properly consider and document all of the 1.8 .. 1.10
compatibility issues at once.
But #1 : as I said above, I'm pretty sure Ludovic disagrees with this!
But #2 : actually, right now I don't even know in detail what is in
master. I plan to review that soon, and it may be that the detailed
results completely change this.

Huh? That makes no sense to me.

I believe that programmers' natural tendency is to plan for infinite
compatibility.

There you're right. We can and should rip GH out now. Actually that
might make an excellent first example for documenting incompatibility.
(Anyone who really still needs it can take on the burden of
maintaining the GH layer themselves.)

Are there items in master now that you are particularly wanting /
waiting for? I guess the GC is one, any others?
