My gut reaction is that I don't want to be creating a table of contents list of sections by hand.

I feel it's a design error to require the sections be listed at the top and named below. If I want to change a name below, then I have to remember to make the identical change above.

Unless there's something obvious I'm missing about how literate programming works, it seems like a "generate table of contents" macro would be vastly superior to having to maintain it by hand.
