[Pharo-dev] Anonymous classes in Pharo 3 - must be instances of Class, not Behavior

[Oscar Nierstrasz]

Hi folks,

I was updating my lecture on Reflection for the Software Design and Evolution 
course, and I see now that anonymous classes can no longer be instances of 
Behavior but must be instances of Class.  If you try to compile a method on an 
instance of Behavior, it fails.  (basicLocalSelectors is not understood)

Am I missing something?

Cheers,
Oscar

testPrimitiveChangeClassTo
        | anonClass browser |

        anonClass := Class new. “must be Class, not Behavior"
        anonClass superclass: Browser.
        anonClass setFormat: Browser format.

        browser := Browser new.
        browser primitiveChangeClassTo: anonClass new.
        anonClass compile: 'thisIsATest ^ 2'.

        self assert: browser thisIsATest = 2.
        self should: [Browser new thisIsATest]
                raise: MessageNotUnderstood.
