Whoa, folks! Can I ask the gentlemen to curb their enthusiasm?

PEP 343 is still (back) on the drawing table, PEP 342 has barely been implemented (did it survive the AST-branch merge?), and already you are talking about adding more stuff. Please put on the brakes!

Yes. PEP 342 survived the merge of the AST branch. I wonder, though, if the Grammar for it can be simplified at all. I haven't read the PEP closely, but I found the changes a little hard to follow. That is, why was the grammar changed the way it was -- or how would you describe the intent of the changes? It was hard when doing the transformation in ast.c to be sure that the intent of the changes was honored. On the other hand, it seemed to have extensive tests and they all pass.
