    <thetext>Currently op_wide16 and op_wide32 only apply to the next instruction. But looking at examples, they often seem to be repeated for every instruction in some large sequence.
So I&apos;d like to test having op_toggle8, op_toggle16, op_toggle32, that apply to all instructions until the next toggle. It should both save some memory and ideally some dispatching overhead.</thetext>
