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.
