Issue 16947: Class-side Inst Var "#name" Allowed, But Breaks System https://pharo.fogbugz.com/f/cases/16947/Class-side-Inst-Var-name-Allowed-But... If you like adventure, try the following: class := Object subclass: #MyClass instanceVariableNames: '' classVariableNames: '' category: 'MyBug'. class class compile: 'break name := 1'. class break. MyClass browse "Emergency evaluator :/" To restore the system: class instVarNamed: #name put: #MyClass. Now here's the kicker - there doesn't seem to a class-side instVarNamed: #name! It's not defined in Object or ProtoObject. NB. Also a bug in Pharo 4.0 ----- Cheers, Sean -- View this message in context: http://forum.world.st/Woe-unto-thee-who-assigns-to-class-side-name-tp4859734...
