DTC: Remove the need for the GLR Parser.
Previously, there were a few shift/reduce and reduce/reduce
errors in the grammar that were being handled by the not-so-popular
GLR Parser technique.
Flip a right-recursive stack-abusing rule into a left-recursive
stack-friendly rule and clear up three messes in one shot: No more
conflicts, no need for the GLR parser, and friendlier stackness.
Compensate by reversing the property list on the node.
