Here's my second Haskell project. https://github.com/karun012/arion . It associates source files with test files, watches the file system, and when a file changes it runs the corresponding test files instead of running all the test files. I made this to make the process of red-green-refactor faster.Would love to get feedback.
Thanks to Simon Hengel for adding a link to my project on hspec.github.io.
