What is a young Smalltalker to do? SmallLint forcefully suggests that:

^ Preferences optionalButtons
    ifTrue: [OBFixedButtonPanel new]

should be rewritten as:

^ Preferences optionalButtons
    ifTrue: [OBFixedButtonPanel new]
    ifFalse: [nil]

which would be fine, but as soon as I try and pretty print the
rejigged method, it reverts to the version without the ifFalse:
clause?

Two tools enter, one tool leaves. But which one?
