Comment (by goldfire):

 I'm a little lost now. It looks like `pretty` already has the annotations
 proposed in comment:3. So is #10735 really all that's left to allow
 annotations within `SDoc`s? And I remember somewhere that color would be
 impossible without a design like comment:3... and yet we have color now.

 Re comment:52: I like this idea a good deal, and I'll admit it's where I
 started my thinking about this problem, but then comment:3 seemed to go in
 a different (but quite worthwhile) direction.

 So I guess the direct question is: what should my student and I work on?
 Adding annotations to `SDoc`s seems redundant. Tackling #10735 will likely
 be beyond her level of experience. So I'm tempted to steer her toward
 comment:52... but I'd love some feedback before we start getting in too
 deep in one particular direction.
