Hi all, strings in Playground are read only in Pharo 9.0 Build 1153 so that
'hello' at: 2 put: $a; yourself ctrl+p This throws an error: „Modification forbidden: ‚hello‘ is read-only, hence its field cannot be modified with $a which is actually a very nice error message but is this supposed to happen? The example does work in Pharo 8 without problems. Greetings Markus
