enter_trace(tid, type, obj, invoker, klass, mid, *args)
  1. If arguments are required to trace, try using kernel inspect to print it
  2. If obejct is required to trace, try using kernel inspect to print it.

Otherwise print class name, The inspect can cause recursion and blow up ruby. Rescue only delays the issue hence not used here.

  1. Show the last caller and line
