Subject: [Boost-docs] [quickbook] Several template bugs & Turing-completeness

I've found several bugs regarding templates in Quickbook from 1.35 release:
1. This does not work:
[template sitelink[page name] [@http://site.org/[page] [name]]]
[sitelink index.html here] <- "error: Expanding template"
2. This causes access violation (memory write):
[template join1[a b] [b][a]] <- "error: Expanding template"
[template join2[a b] [a][b]]
[template test[x] [join1 [join2 0 [x]] 0]]
3. It would be nice if this worked:
[template t1 foo]
[template t2[t] [[t]]]
[t2 t1] <- "error: Expanding template"
4. Sometimes, when a matching ']' is missing, Quickbook hangs with 100% CPU
usage. However, I don't have any code snippet causing this right now.
BTW, in the docs there is a statement that Quickbook is Turing-complete. This
made me curious, but I haven't figured out yet how this works. Could somebody
send an example of some simple algorithm executed using Quickbook? Thanks in
