class_docstr: Modified Pdb class, does not load readline.
  
  for a standalone version that uses prompt_toolkit, see
  `IPython.terminal.debugger.TerminalPdb` and
  `IPython.terminal.debugger.set_trace()`
  
  
  This debugger can hide and skip frames that are tagged according to some predicates.
  See the `skip_predicates` commands.
