(function() {
var cache = {};

// Figure out if we're getting a template, or if we need to
// load the template - and be sure to cache the result.
var fn =

?
cache[str] = cache[str] || tmpl(document.getElementById(str).innerHTML)
:
// Generate a reusable function that will serve as a template
// generator (and which will be cached).
new Function(
"obj", "var p=[],print=function(){p.push.apply(p,arguments);};" +

// Introduce the data as local variables using with(){}
"with(obj){p.push('" +

// Convert the template into pure JavaScript

// Provide some basic currying to the user
