This is the code that uses assignmentNodes: ((Point slotNamed: #x) assignmentNodes collect: [ :each | each methodNode compiledMethod ] ) asSet But as a downside, it has to create the AST. So maybe better is to use the API of the Variable: Point methods select: [ :each | (Point slotNamed: #x) isWrittenIn: each ] This is implemented to scan on the bytecode level for InstanceVariableSlot and thus is much faster: InstanceVariableSlot>>#isWrittenIn: ^aCompiledCode writesField: index

Yes, to a variable (so including slots and all) you can ask readNodes and assignmentNodes (accessingNodes gives both). It gives nodes from the AST, but from there you can obtain the methods and everything.

A variable can have references. Those references can be split into readers and writers of the variable. Can Pharo list readers and writers separately? Thanks, Aik-Siong Koh
