I added vsum to the core library so we shouldn't need it here.

Isn't this the same as calculating the signed area? Maybe we can modify signed_area to optionally accept a face parameter instead of having two different functions.

It's doing something very similar. (Well, it should be doing something very similar. I think that might be incorrect as submitted.)

The name of this function is a little too general I think. And I'd call it more of a vector "slice", than a "range".
How about "slice_circular" or "vslice_circular"?

Also, maybe this should go in "utilities" section of functional.scad.
Do you think it would be useful in other circumstances, or do you feel its just a very niche thing that would not be needed again?

It seems like a general thing, but I don't have a lot of experience developing this kind of thing.

Add underscores between words in name. At first glance it looks like you misspelled "linear"

Can you create a separate PR for independent features (rounded cube, vs triangulate)?
When you submit a PR it accounts for ALL differences between my branch and yours. So typically if you have multiple changes you are working on concurrently, you would develope each independent feature in its own branch, then make the PR.

What's the best way to do that now that I've got both in on my local version?

Probably easiest to delete roundedcube.scad in your master, then we can focus on this PR striclty for the triangulation feature.
Since this PR came from your master branch, any updates to your master will update this PR automatically, until the PR is closed.
Then create a new "rounded_cube" branch. Ideally you would create this branch this from your master at from the commit just before you added triangulation.
git branch branchname <sha1-of-commit>
Your roundedcube.scad will still be in your git history, and you can re-add it in this branch.

A rounded cube 'primitive' that uses cube/octahedron duality and face triangulation capability to help with subdivision.
