// - '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
