BTW, the ``__`` syntax is now implemented. There have been some changes to
the doc tree though: "reference" replaces "link", and "target" now uses a
"refuri" attribute to hold what used to be data (the data is now used for an

You didn't look back far enough, and your search may have been too
specific (try searching for only "nest"). Try, for example, Ed Loper's
2001-03-21 post, which details some rules for nested inline markup. I
think the complexity is prohibitive for the marginal benefit. (And if
you can understand that tree without going mad, you're a better man
than I. ;-)
Inline markup is already fragile. Allowing nested inline markup would
only be asking for trouble IMHO. If it proves absolutely necessary, it
can be added later. The rules for what can appear inside what must be
well thought out first though.
