Agreed. Will implement read side. I think I agree with Eric and you on
the bitmask now. It should not add much complexity, I think. I'll work
on adding it. Given that _bus() isn't appropriate anymore, how does
"gpio_set_values" and .sets sound and correspondingly gpio_get_values
and .gets?

Thanks,
