    """This maps a node name to a stack trace in the source code.
    The map key is a mangling of the containing function and op name with
    syntax:
      op.name '@' func_name
    For ops in the top-level graph, the func_name is the empty string.
    Note that op names are restricted to a small number of characters which
    exclude '@', making it impossible to collide keys of this form. Function
    names accept a much wider set of characters.
    It would be preferable to avoid mangling and use a tuple key of (op.name,
    func_name), but this is not supported with protocol buffers.
