Type-checking your whole Pull Request before submission

You want to make a pull request to a Haskell project, which requires that each commit in your PR compiles fine individually.

Here is an easy, automated and fast way to check it:

git rebase --interactive HEAD~~~ --exec "! grep 'error:' <(stack ghci mylibrary:lib --ghci-options='-e 1' 2>&1)"

                frame.f_lineno = lineno
