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
