Special defs?  Apologies, I'm new to the docs list.  Currently I can
just talk all of those [def X [link X /X/]] macros, extract and
alphabetize the X's, put them in a section called "index", and I have
a kind of glossary/index (glindex?), a list of links to each X's
"primary" docs location.  But only in html, not in fo-generated pdf.
I'm curious as to how you like to generate your indexes.

Ah, I'd missed that.  Personally I think that's the way to go.  With
unscoped includes and scoped macros, the behaviour is generally more
consistent with C++.  One could even adopt a convention of .qbk for
quickbook files and .qbh for quickbook "headers" of macros.  One could
concievably even enforce a one-definition rule for macros (though I
don't have a good feel for how much trouble that would save people in
the long run).

Awesome.  "for" loops, too?  (wink) 

Anyhow *this *particular *syntax is irrelevant, !anything _would
