You can define a method "=>" in Object as: => aBlock ^ aBlock value: self That would allow you to write expressions like this: 7 => [ :x | x+3 ] => [ :x| x*3 ], if you further define "=>" in Array as: => aBlock ^ aBlock valueWithArguments: self you are able to write your example: (([ :f :g |

Not knowing your specific usage, this tends to happen if you have an instance of class X, and then remove the class. To save the instance from going stale, Smalltalk has always made an Obsolete class. You can find the offending X instance by inspecting this: ReferenceFinder findAllPathsTo: X
