Re: Pointer to generic type with unspecified generic parameter?

@monster Why not use inheritance?
    
    
    type
      ThreadID* = distinct uint8
      
      AnyMsg = object {.inheritable.}
        sender*: ThreadID
        receiver*: ThreadID
        previous: ptr[AnyMsg]
      
      Msg*[T] = object of AnyMsg
        content*: T
    
    let space = alloc0(sizeof(Msg[int]))
    let m = cast[ptr[Msg[int]]](space)
    let p: ptr[AnyMsg] = m.previous
