The only thing is, there already is a decided way to do it so far as I can see...Like the decision about which side of the road cars should drive on, it really doesn't matter *which* choice is taken, as long as *something* is decided.
Other languages use "this" and "self", so what is wrong with $?SELF which is only a sigil longer than those used by other languages? Perl has always had sigils, but there's little complaining about having to write them in other contexts. Admittedly it's uppercase too - maybe lowercasing it would make it easy enough to type? But inconsistent with other $?WHATEVER style variables perhaps...I've seen other languages use "this", "self", and even "me", and few people complain about a particular language's choice. (My suggestion would be "o" or "O", as suggested in another thread, but I'm certainly not attached to those keywords.)
