The second commit (6ef5d42b93e0bf466e491a96ea5a748ea913538b) is the one that needs to be reviewed. The first commit (eea79e407058f2d33cdffd91bded3144728ff0be) is just there to be able to use the test file that isn't empty that will be added soon (https://github.com/exercism/nim/pull/339). Without this, the CI fails (see this run) because the manipulated test file is invalid thus compilation fails.
