Haskell web frameworks—first impressions

I'm currently exploring Haskell and how suitable it would be for web development. I've been toying around with Haskell a little previously, but I have absolutely no idea of what to expect when it comes to web frameworks in Haskell. I'm currently looking at two alternatives: [Snap][snap] and [Yesod][yesod]. I thought it might be useful to record my first impressions and observations as I experience them. Perhaps material for a future blog post…

Installation

I'm installing Snap version 0.4.1 and Yesod version 0.8 on two machines running Mac OS X 10.6.7, Xcode 4.0.2, GHC 7.0.3 (trying both 32 and 64-bit versions) and Haskell Platform 2011.2.0.1.

I was happy to note that both of the frameworks are available from cabal. That means installation should be easy, right? Well…
