That is a good observation :).
You do not like the underscore, or the "sel" entry?
If you talk about the underscore, I just wanted a way to distinguish between special variables. You also see the same "notation" in the debugger (variables like _self and _thisContext).
If you talk about the entry altogether, this part is more experimental. Some people did not like the printout in the comment, and then I added _self to show the print string next to it. I am still not decided on showing it. What do other think about it?
Cheers,
