Does it actually make sense of this to be a module? I guess it's harmless.

97–98

I find it a little odd to be providing both of these things in one file, but I don't have a feel for what makes "good" use of JSON.

Oh, likely no.

97–98

I find it a little odd to be providing both of these things in one file, but I don't have a feel for what makes "good" use of JSON.

I'm unsure as well, but I'll see if I wind up needing it. after noticing this after the commit (I missed it before somehow) I got to thinking about it and maybe it's not needed. It can be inferred by looking at all the other syscalls. It only saves about 50 lines in the output.
