Borrow . doesn't work with distinct generic object

[jangko]

Description

type
  Vehicle[C: static[int]] = object
    color: array[C, int]
    
    
  Car[C: static[int]] {.borrow: `.`.} = distinct Vehicle[C]
  
  
  MuscleCar = Car[128]

The manual says {.borrow: ..} can works with distinct object, but apparently not with distinct generic object.
