Reducing software dependencies is one way to reduce an application’s attack surface. I’ve laid out how perlimports can be used to manage and reduce Perl dependencies in both modern and legacy applications. It’s not difficult, but it should be done with care.

When you’re constantly producing code and documentation, mistakes will happen. Some will be easy to spot and others may elude you. We know that attention to detail counts.

In order to avoid the impression of carelessness, let’s automate the finding and fixing of typos.

When you find variables which have not been used, you may find yourself asking, “why is this here?” and you may not easily get an answer.

So, we want to make sure we can remove old bits of unused code and also prevent new cases.
