Hi Marcel,

thank you for the clarification. In this case, I will have to rethink when traits are actually useful ... But eventually, I will find a convincing usage example someday. :-)

Best,

Christoph

Hi Christoph,

traits are woven into the class where you use them. This means that you can actually overwrite the included traits as you did in your example. And Object DNU #foo. That's expecetd. :-)

Hi all,

I just was trying to activate a super method from a trait but got a DNU:

MyTrait >> #foo ^0

Object subclass: MyObject uses: MyTrait.

MyObject >> #foo ^super foo + 1

Is this not how traits are expected to work? Or is there any other way to reuse the default logic specified in the trait? Do I need to return to traditional inheritance in order to achieve this?

Thanks in advance!

Best,

Christoph
