It's in the 'collections' vocabulary category.

Search is your friend.

Of course, I only started using the search facility at SqueakFest, but it's a 
great tool.

It should have already done this, I think.

Also, Scott added an interesting feature where if you put an object's *tile* 
into a Holder and then use the "tellAllContents:" command, the named script 
will be run on the object that the tile refers to.

No, it won't do that.
