  Types:
    -type match_variable() :: atom().
      Approximation of '$1' | '$2' | '$3' | ...
    -type trace_match_spec() ::
          [{[term()] | '_' | match_variable(), [term()], [term()]}].
    -type trace_pattern_mfa() :: {atom(), atom(), arity() | '_'} | on_load.

  The same as [;;4merlang:trace_pattern(Event, MatchSpec, [])[0m, retained
