There is a very useful error log that prints if I don’t recuse an exception from within a GenServer.

GenServer {[GENSERVER NAME HERE]} terminating
  ...
Last message (from #PID[PID HERE]): [ARGS TO THE HANDLE CALL HERE]
State: [GENSERVER STATE HERE]

I’ve dug around the elixir code base but can’t find how {'** Generic server ' ++ _, [name, last, state, reason | client]} is getting set in elixir/lib/logger/lib/logger.ex. Most importantly I want last (which is [ARGS TO THE HANDLE CALL HERE]) for my own logging purposes. Hoping someone has a way to access this in the recuse block of a try and not an answer that involves somehow storing the message args from the handle_call function…
