But that does't work in the case the object you are looking for nil... (Ok,
maybe that's not a really relevant case...)
This version however handles the case,
detect: aBlock ifOne: presentBlock ifNone: noneBlock
| result |
result := self detect: aBlock ifNone: [ ^ noneBlock value ].
^ presentBlock value: result
