There's dialyxir which is wrapper to Dialyzer and I found it work fine on pure (non Phoenix) code.

As for how the problem manifests: even obvious contract violations stops being shown (making it feel like "Dialyzer is useless") but the second tell is very long check times (tens of seconds up to minutes).

Cool, cool.

  [W]hat happens when you run Dialyzer against BEAM files compiled from Elixir that has circular dependencies? Do its reports become more reliable, or does the reliability of those reports become irrelevant because the transformations the Elixir build system makes to your code make the structure of the BEAM code difficult to trace back to the Elixir source code?
