While we're talking about template engines, there's a little piece of
code by Rici Lake which is astounding for its power/weight ratio:

http://lua-users.org/wiki/SlightlyLessSimpleLuaPreprocessor

I pulled it out in slightly modified form as:

http://snippets.luacode.org/snippets/Lua_Preprocessor_118

(It's not often that such functionality can fit into the conventional
size of a snippet!)

The cool thing is that Lua code and HTML (or anything) can be freely mixed

<ul>
# for i = 1,10 do
   <ld>$('Hello '..i)</ld>
# end
</ul>

Only two rules (a) lines starting with # are Lua and (b) otherwise Lua
expressions can occur in $(...)

The code is well worth studying for the 'aha!' moment.
