Chris@13 10 *
Chris@13 11 * The normal anonymous class structure violates assumptions about the order of token offsets.
Chris@13 12 * Namely, the constructor arguments are part of the Expr\New_ node and follow the class node, even
Chris@13 13 * though they are actually interleaved with them. This special node type is used temporarily to
Chris@13 14 * restore a sane token offset order.
