So do I, and that's why I'd like to err on the side of having smaller
I think the main reason the tree-based index format never made it is
that the in-core APIs were not set up to make use of the new index
format. I'm also still interested in getting it in, but I haven't
found the time for looking at making the index code pluggable yet. It
would probably take a similar refactoring as with the refs code to get
All that said, GSoC was still a great experience for me, and I got to
learn a ton over the summer. But I did feel like I let the people
that invested a lot of time in the project as well down a bit, by not
being able to finishing the project. And having the feeling of
accomplishment of actually finishing a project would definitely have
been nice to have as well. So for those reasons I think it would be
better for students to take on smaller projects.
