Ran into the below in Squeak 4.2. The method is present and almost unchanged in Cuis, along with the flag, and it's there in Pharo too. I'm curious if anyone knows S.D., or why S.D. thinks #ThisMethodShouldNotBeThere. Nothing like a good mystery! CC'd a couple folks who could be S.D. (Ray is sD on squeaksource.)

I was tempted to simply append

self flag: #OhReallyWhy? "cbr"

...and ship it off to all three forks just to be a stinker, but I resolved to send this email instead;)
