    ^self basicNew
        initialize;
        setRow: aString;
        yourself.

You’re sending initialize, setRow: and yourself to the restult of self basicNew, and returning (^) the value returned by the last message in the cascade (ie, yourself).

The cascade you wrote the in the main article was sending basicNew, initialize, setRow: and yourself to self, which isn’t quite what you wanted.

I’m glad you enjoyed it.
