Arbitrary Haskell

This Haskell library provides an instance of QuickCheck’s <code>Arbitrary</code> typeclass, which produces <code>String</code>s of Haskell code.

Specifically, we define <code>newtype Haskell = H String</code>, and give it an instance of <code>Arbitrary</code> which orchestrates the generation of well-typed Haskell expressions (using the <code>haskell-generate</code> library) then pretty-prints the results.
