bulk .importc

[SerjEpatoff]

I want to import some constants from Linux C headers, so I write code like this:
    
    
    var
      SYS_read {.importc, header: "<sys/syscall.h>".}: clong
      SYS_write {.importc, header: "<sys/syscall.h>".}: clong
      SYS_open {.importc, header: "<sys/syscall.h>".}: clong
      SYS_close {.importc, header: "<sys/syscall.h>".}: clong
      SYS_stat {.importc, header: "<sys/syscall.h>".}: clong
    ...
    
    
    Run

Good, but too repetitive. I want to reduce verbosity, like:
    
    
    var {.importc, header: "<sys/syscall.h>".}
      SYS_read : clong
      SYS_write : clong
      SYS_open : clong
      SYS_close : clong
      SYS_stat : clong
    ...
    
    
    Run

or
    
    
    var
      {.importc, header: "<sys/syscall.h>".}
        SYS_read : clong
        SYS_write : clong
        SYS_open : clong
        SYS_close : clong
        SYS_stat : clong
    ...
    
    
    Run

?

Last 2 variations are not working, so is it possible to somehow apply 
`{.importc...}` to all underlying identifiers?
