Yesod is based on templates, to generate instances for listed entities, and dynamic content process functions through Template Haskell constructs called QuasiQuotes whose content is translated to code expressions by metaprogramming instructions. Light-weight syntax A lot of web development is boilerplate.
But after writing a small application with Snap which is modular and very understandable for newcomer I could easily identify the same patterns in Yesod and write Yesod applications easily with greate help from Yesod book.
