Conference call September 5 2006 8:00am-10:00am EDT
All present by about 8:02am EDT:
Kent, Anton, Matthew, Mike, Will
Thanks to Kent and Mike for all the work they've done...
0. finalize agenda (1 minute)
1. action items from 8/29/2006 (5 minutes)
- publish the not-for-public-release r6rs
2. termination language for identifiers, characters, etc. (5 minutes)
- are termination requirements the same for all of these?
- who will fix the language?
Second paragraph of 3.2.1 should become something like:
Lexemes that require implicit termination (identifiers,
numbers, characters, booleans, and dot) are terminated
by any <delimiter> or by end of file, but not necessarily
by anything else.
3. export "for" syntax" (10 minutes)
- there are different interpretations about the semantics and
disagreement about the proper interpretation mong current
designers/implementors (Flatt, Dybvig, van Tonder, Ghuloum)
- the export "for" syntax turns out also to be essentially redundant
- recommendation: flush export "for" syntax and state that
exported bindings within a library are exported for run, and
reexported identifiers are exported into their import phases
Matthew so moved; Kent seconded.
yes: Kent, Matthew
abstain: Will, Anton, Mike
At what phases should the standard libraries be exported?
Matthew suggested that (r6rs base) export everything
for run only, and that (r6rs) export everything
for both run and for export.
Why is eval in the (r6rs) library?
Will moved that eval be removed from (r6rs) library;
Kent seconded. Motion carried by unanimous vote.
4. script syntax
- ignore first line iff it starts with "#!<space>" or "#!/"?
- ignore first line regardless?
An R6RS script has <blah> as its first line.
Implementations are required to ignore the first line
of a script, even if it is not <blah>.
5. perceived r6rs size (10 minutes)
- should we make use of headers, page breaks, Part numbers, etc. to
make clear distinction between base and libraries?
- should we add a rationale for the size and explain that the base
is approximately the size of r5rs?
- should we mention that r6rs is the first Scheme standard that a
reasonable Scheme implementor might choose *not* to extend?
6. six-month public comment process (15 minutes)
- expectations for editor participation
editors are expected to participate
we don't have to present a unified front
editors may make public comments
editors will also deliberate in private
- tracking public comments
- tracking our own deliberations
- trac wiki?
Mitch suggested we set up two mailing lists.
Anyone could submit to one, but only Kent could read it.
Kent would verify that it is sent in the proper form.
Then Kent would resubmit the comment to the second list,
where everyone could participate.
Kent didn't want to do that task manually.
Kent suggested they delay public comments for a week
so we can put together a web form that would enforce
the correct form. Those comments would be sent to
Kent. The editors would be obliged to respond to
those comments, but not to comments sent to the
Kent volunteered to do the web form.
Will volunteered to set up a Trac system for the editors.
Only the editors will have access.
Anton volunteered to look into other systems that might
have a more automated submission process.
Mailing list will probably be at r6rs.org.
The editors should not be managing that mailing list.
7. publishing discussion archives
- where and when
Kent feels the archive should not be published
until after the R6RS is accepted.
Let's think about this for a week.
8. publishing reference implementations
- where and when
when: some (possibly preliminary) version by next Wednesday
except as noted below
libraries and syntax-case
Kent, maybe another from van Tonder
Unicode reader (as part of i/o, probably by next Wednesday)
hash tables (maybe by next Wednesday)
exceptions and conditions
list utilities (don't forget tortoise and hare)
i/o (in October)
Meet again next Tuesday, same time.
The week after that is ICFP.
9. adjourned about 9:45am EDT
