[Pharo-dev] Question on AST

Hello, I'm working on code manipulation on Pharo using the AST. Recently, I ported my code to Pharo 5 and some of my tests are not running anymore. Specifically, if I have a method as follows: method | variable | variable := 'String'. In Pharo 4, when I get the tree, I have a RBTemporaryNode representing the declaration of the variable, and a RBVariableNode for the assignment at the third line. In Pharo 5, I have two RBVariableNode's for both cases. And when I call #isTemp I get a MNU because the return of #binding is nil. How can I now differentiate these two nodes in the example? Is this a bug or a feature? :-P Cheers, -- Gustavo Santos
