With your advice, my code is finally shaped as following:

https://github.com/fpiot/chibios-ats-2/blob/720847a31b9417ee267a34bf1746802e916ce03b/demos/STM32/RT-STM32F746G-DISCOVERY-LWIP-FATFS-USB/main.dats#L64

The code is type-checked, and captures system state for ch* function well.
However the code can't catch the error such like following:

```
extern fun chEvtObjectInit (!chss(10) | cPtr0(event_source_t)): void = "mac#"
```

I think ATS compiler can capture the error, if it supports int's
bounds depended by absvtype `chss`.
I hope the supporting becomes in future.
