  Why ?
  Sorry if I made a…

  Just started using this last week and its great. Even integrated it in to our automated build script, so it runs every commit.

• Neil Bowers commented on Check your test coverage with Devel::Cover

  Robert: good to hear.

  Maybe you could write a blog post about your experiences with Devel::Cover, and how it's helped you? Doesn't have to be long — it's good to hear a range of perspectives and experiences.
