Haskell beginners' workshoppe

Details
We learn how to solve simple but common problems using the Haskell language. We start off with a quick presentation about the workshoppe and the tools we'll be using. Then we hack! There's plenty of fun exercises. The goal of this first workshoppe is to make you comfortable in solving problems in a functional style of programming.
Following our first meetup[0], we agreed to set up a new one straight away. And we agreed that we'd like to see some "real world" code, but conceded that a more beginner friendly meetup was probably in order before we go quite that far.
This meetup is a compromise between learning the basics and seeing "real world" code -- we learn the basics by solving common problems. Most languages (Haskell included) already come with a base library that solves things like finding the length of a list, doing a logical AND, concatenating text, and so on. In this workshoppe we implement things like these ourselves.
N.B.
Bring a laptop! If you have GHC (the glorious Glasgow Haskell Compiler) installed, that would be very advantageous. We will be writing code and running it in the GHC REPL, called GHCi. If someone is unable to install GHC, we will try to provide some tech support at the meetup.
