I think it is a bug related to the recent adoption of Unicode as the default string representation in Cuis because : (String withAll: 'hello') == (String withAll: 'hello') copy => false Adoption of Unicode as the default string representation in Cuis is an important change impacting many area and external package of Cuis. So it mY take a few cycles to get it bug free but it is a big win in the long term. </blockquote> Yes. UnicodeStrings can not be modified (they are effectively immutable), so #shallowCopy and #copy just answer the receiver. We'd need to update the CuisBook.
