Time for a new Erlang story, kids! This one is about one of my favourite Erlang tools: dialyzer.
You may know this already, but I always recommend checking all your Erlang code with dialyzer as soon as you write it. You can hear me preaching that exact thing at this Functional Geekery interview. We’re so fond of these tools (like dialyzer, xref and elvis) at Inaka, that we even created Meta Test Suites that you can use to run dialyzer as part of your common test suites every time.
