I think IHP for learning Haskell has the same flaw that Rails always did. You have no idea what is part of the language and what is part of the framework. You'll get stuck once you stray from the golden path.

I'd recommend starting with Scotty instead. It's much easier to understand what it is doing. Use Lucid for HTML rendering, and your choice of DB libraries (I like Selda). These all avoid template haskell and don't rename any prelude functions. If you add them one at a time you'll see what each one is offering and understand where to go when you need to do something more complicated
