>>From the CHANGES-2.7.2.txt:
"Bad code gen with ^ or ! on tree root
when building trees in a tree walker grammar such as:
expr: #(PLUS^ expr expr)
Fortunately, ^ is simply redundant; removing it makes code ok.
Added a warning. Added an error message for ! saying that it
is not implemented."
Are the ^ and ! not implemented yet or they are gone forever?
