You are totally right. It's not getting me here, but I am running into a problem using ANTLR's visitors to deal with what kind of storage opcode to use when running into an assignment. I only roughly pondered it in my head but never really looked at the AST Python was generating for clues.
But, you see, my cat is hungry and I have to, you know, ... take care of him. A lot. For awhile. Yeah. ;)
