How to see all function invocations for a process?
In “The Soul of Erlang and Elixir”, Saša Jurić had some custom code to trace function invocations in a process and return the first 50 invocations or all invocations in 1 second, whichever comes first. But he didn’t show the code behind the function he called.
How would you do that? (My guess is that it uses recon somehow.)

You’ll probably be better off using recon or redbug in real prod.

Just reading it, I have no idea why I’m calling trace twice, returning an error if the second one fails. A single trace call followed by a call to trace_pattern should work.
