The documentation on the website seems to have lost the numbers
identifying the various sections. It was useful to point a user to e.g.
§3.6.2 of the libref in order to guide them to the string interpolation
documentation. This is now no longer possible, and instead the user must
hunt around for the appropriate section. This is a severe usability hit
against the documentation.

I disagree that missing section numbers are a severe usability hit.
Especially in the context that the new docs are constantly updated,
there's no telling when section numbers will shift, misleading those who
only navigate by section number. In contrast, a link is persistent and
usually also quicker to get to.

That said, I acknowledge the wish for section numbers, and there is an
issue entry about it in the tracker for the Sphinx project, which is
used to build the new docs, at <http://code.google.com/p/sphinx>.

Closing this one as duplicate.
