Shakespeare is a family of type-safe, efficient template languages. Shakespeare templates are expanded at compile-time, ensuring that all interpolated variables are in scope. Variables are interpolated according to their type through a typeclass. Shakespeare templates can be used inline with a quasi-quoter or in an external file. Note there is no dependency on haskell-src-extras. Instead Shakespeare believes logic should stay out of templates and has its own minimal Haskell parser. Packages that use this: shakespeare-js, shakespeare-css, shakespeare-text, hamlet, and xml-hamlet. WWW: http://www.yesodweb.com/book/shakespearean-templates
