Hi,
This is just a one-liner to add to the framework, but that makes it even
more fun: One-Shot links.
A link now can have the #optionOneShot, which means that it will
de-install itself when activated for
the first time:
link := MetaLink new
                metaObject: self;
                options: #(optionOneShot);
                selector: #tagExec.
The full test looks like this:
testLinkOneShot
        | sendNode link |
        sendNode := (ReflectivityExamples>>#exampleMethod) sendNodes first.
        link := MetaLink new
                metaObject: self;
                options: #(optionOneShot);
                selector: #tagExec.
        sendNode link: link.
        self assert: sendNode hasMetalink.
        self assert: tag isNil.
        self assert: (ReflectivityExamples new exampleMethod = 5).
        self assert: (tag = #yes).
        self deny: sendNode hasMetalink.
        tag := nil.
        self assert: (ReflectivityExamples new exampleMethod = 5).
        self assert: tag isNil.
