intro-to-parsing-stack

This repo is going to:

• reorganize the programs in Jake Wheat’s introduction to parsing with Haskell and Parsec according to Stack’s convention,

• test all programs with latest GHC and parsec package.

In this initial version, we use old --resolver=lts-3.22 (GHC 7.10.2), parsec == 3.1.9, making the environment as similar to the author's as possible.

Now we use --resolver=lts-11.8 (GHC 8.2.2), - parsec == 3.1.13.0.
