Haskell solutions for 2016 Advent of Code
These little solutions are optimised for tidiness rather than speed of writing. In some cases I've code-golfed them for performance or elegance, in the interest of learning new tools and techniques.
With stack installed:
stack setup
stack build
stack exec adventofcode2016 [DAYNUM]
where DAYNUM is the number of one of the days of Advent!
