+//## TODO possible enhancements: [FlavioJS]
+// - 'callfunc' supporting labels in the current npc "::LabelName"
+// - 'callfunc' supporting labels in other npcs "NpcName::LabelName"
+// - 'function FuncName;' function declarations reverting to global functions
+//   if local label isn't found
+// - join callfunc and callsub's functionality
+// - remove dynamic allocation in add_word()
+// - remove GETVALUE / SETVALUE
+// - clean up the set_reg / set_val / setd_sub mess
+// - detect invalid label references at parse-time
