This works
```
        m.d.comb += [
            *[kled.o.eq(1) for kled in kleds],
            kleds[0].oe.eq(self.current_led.count[2:] == 0b00),
            kleds[1].oe.eq(self.current_led.count[2:] == 0b01),
            kleds[2].oe.eq(self.current_led.count[2:] == 0b10),
            kleds[3].oe.eq(self.current_led.count[2:] == 0b11),
        ]
```
This does not work
```
        m.d.comb += [kled.o.eq(1) for kled in kleds]
        for i in range(4):
            m.d.comb += \
                kleds[0].oe.eq(self.current_led.count // 4 == i)

```
