Heh, "expand on this template". :)

I mentioned an old version of this library a long time ago, and I think 
Untyped released something similar.

Here's a simple example, which doesn't demonstrate all the features:

  (html-template
    (html (head (title "Foo & Bar"))
          (body (h1 (*value* essay-title))
                (p "Bunnies are nice." (br) "Yep."))))

expands to:

  (begin (display "<html><head><title>Foo &amp; 
Bar</title></head><body><h1>")
          (write-html essay-title)
          (display "</h1><p>Bunnies are nice.<br />Yep.</p></body></html>"))

Compared to the traditional dynamic lists with SXML and xexprs, it's 
easier and less error-prone to code, more static checking is possible, 
and plausibly better run-time performance.

I've been refining the language in 4 new libraries, as one library 
informs another.
