A way to get a real argument type in a proc call?

[mmcol]

main.nim
    
    
    import std/macros
    
    macro printType(n: untyped): untyped =
      result = n
      echo n.intVal, ": ", n.getType()
    
    proc test(a: int, b: int16, c: int32) =
      discard
    
    proc main() =
      test(
        1.printType(),
        2.printType(),
        3.printType()
      )
    
    main()
    
    
    Run

This prints (at compile time):
    
    
    1: int
    2: int
    3: int
    
    
    Run

But I expected this (at compile time):
    
    
    1: int
    2: int16
    3: int32
    
    
    Run

I need a way to get a real argument type in a proc call.
