Yes, you're right :)
You find the use of Symbol>>#value: "too meta"? I like it as a good readable shorthand.
Best,
Christoph

ifNil: ['']
This changes the order so that the non-exceptional case is first. It also avoids the meta-level.

I'd leave out the 'ifNil: [nil]' case; it's implied when sending ifNotNil:.
