Hi Kasper,
I've thought about that approach too. But then asked myself whether it is more likely that there is code that relies on this bug than code where this went unnoticed and is therefore broken. What do the other think about that matter and the fix in Squeak? Best, Steffen Kasper Osterbye schrieb am Donnerstag, 28. April 2022 19:03:07 (+02:00): Kasper Osterbye schrieb am Dienstag, 26.
