List,
Could we flag #breaking the way we flag #deprecated?
I think we should hold off deleting the old implementation for at least one
version... Is Squeak's debugger advanced enough to run the old code during
the transition period?
I was thinking #breaking:legacy: or similar to invoke the old
implementation. User flexibility to not need to debug someone else's
library, yaknow?
