Welcome back to the Happy Haskell HAckers Tour. As we approach our next stop, let me firstly apologise for the recent detours. Our bus driver, Yoneda, mixed up the maps and started following the GHC After Dark¹ script. But now we’re back on track, and coming up on your left is our monument to the Haskell literals:

Type-level trickery, UpperCase Haskell, is the showy rock-star of Haskell and all power to the Type. I like a good Type as much as anyone, but what keeps me using the language is the work-a-day value-level coding tool-kit - lower case haskell.

Much advocacy of Haskell, in general, boils down to type-safety and elimination of bugs. How boring. My personal experience is that bugs are trickier in Haskell and I can write bad code in an extraordinary variety of ways.
