And then Peter Uhnak reminded me on Discord about this thread. I'm happy to add the comments, but not sure I understand the issue well enough. IIUC #ast is cached, but #parseTree is not. What I don't understand is the purpose of this difference and when one would use one over the other. For example, when, if ever, would a user want to access a CM's #ast (as opposed to #parseTree) and could modifying it create problems? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
