"#isOdd is not Smalltalk" - doh, I typed it in on my phone and so it just goes to show that it highlights the flaw in chatGPT that others have called out in other languages. I had meant to find some trickier code samples to see how well it does...
Still, it is very interesting how it reasons on this stuff - and I wonder if there is way to tell it about these mistakes? For example is it reading this email (or will it in the future) and understand that it is #odd and not #isOdd.
