ChatGPT has been trained on some outdated “freely available” books. I tried it with the first half of the first question of the Advent of Code 2022 and asked it to write Pharo Smalltalk.
It produced some outdated stuff using messages that are no longer there. FWIW, isOdd was present in Pharo around 2011. > On Mar 15, 2023, at 2:57 AM, Joachim Tuchel <jtuc...@objektfabrik.de> wrote: > > interesting.... > > #isOdd is not Smalltalk, neither Pharo 10 nor VAST 12 understands this > message ;-) > > If I evaluate your snippet -replacing #isOdd for #odd, I get an empty > Collection.
