I'm using the Tracepoint API in my gem and I noticed that when the keyword `return` is used inside a lambda, a block return event (B_RETURN_EVENT) is not triggered. For example, I would expect the same number of B_CALL_EVENT and B_RETURN_EVENT in the piece of code

    TracePoint.new(:b_call, :b_return) do |tp|
      warn tp.event
    end.enable

    a = lambda { return "hola" }.call

    # Output:
    # b_call
    # 
    # Expected Output:
    # b_call
    # b_return 

This seems very similar to issue #8489, so hopefully the fix would be as simple as that one.

Thanks a lot.
