Compiled templates, like [Twig](http://twig.sensiolabs.org/) or [Smarty](http://www.smarty.net/)*, fill this void by
offering a new syntax that has been geared specifically to templating. From automatic escaping, to inheritance and
simplified control structures, compiled templates are designed to be easier to write, cleaner to read and safer to use.
Compiled templates can even be shared across different languages, [Mustache](http://mustache.github.io/) being a good
example of this. Since these templates must be compiled there is a slight performance hit, however this is very minimal
when proper caching is used.
