Hi Erik, You need to make sure you are using the right compiler. In a Pharo3 image, you'll find two compilers: Opal and the old one.
In the old one, you need to change: Scanner>>xColon In RB/Opal, what you can try with your changes is to inspect: RBParser parseExpression: 'a :> 5' And, if you get a RBAssignmentNode, then it is working.
