You are right, this is the way to do it in Self.
What I thought of is slightly different, though. The `value:'
argument gives a name to the element, by which it is then referred
to from within the block. I wanted to leave the element implicit,
to let the block be sort of an external method. The block's code
would look like it were in a method of the element, with
Currently, if I understand correctly, you have to write sth. like
selection do: [|value| value moveBy: distance. ].
I was looking for a way to allow
selection do: [moveBy: distance. ].
For this to work, global behavior would have to include a way to
accept and process such a block (either by a `do:' message or, even
