133 # thing following the whole choice. This is also where the
134 # final "next" pointer of each individual branch points; each
135 # branch starts with the operand node of a BRANCH node.
137 BRANCH BRANCH, node Match this alternative, or the next...
139 # BACK Normal "next" pointers all implicitly point forward; BACK
