i have a compiler Im writing in elixir. I need to trace execution of logic to pinpoint bugs. I have many tests I want to debug individually but I can run only the full test suite. I want to create a couple of macros/functions that'd enable me to debug my code. the scenario I imagine: before the test I want to debug I write Tdd.Debug.enable and then : as the code is being executed, it prints out a tree of called functions, their arguments and return values, effectively building a stacktrace as its being executed. first lets design how we'd print this information and if/what should we store in memory to be able to render it in a shape sufficient for good debugging. Then lets design an elixir module that compiler modules would 'use' e.g. a Tdd.Debug module that'd have and override for elixir def.
