I understand your proposal.  I use "Thread.new (Thread.start)" analogy
(and current set_trace_func analogy).  I think two different behavior is
not good.  Which one do you like?

Yes.

>> `eventN' parameter for TracePoint.trace() is set of symbols.  You can specify events what you want to trace.  If you don't specify any events on it, then all events are activate (similar to set_trace_func).

But there is an issue.  Now "all" means same events that set_trace_func
supports.  But if I add other events like "block invoke", then what mean
the "all"?
