  macro >>`(obj:untyped,temp:untyped):untyped= quote do: discard `obj.`temp`

  Please explain what I'm doing wrong?

  Works for me:

  
  import macros
  
  macro `>>`(obj, temp:untyped):untyped =
    result = quote do: discard `obj`.`temp`
    echo result.repr
  
  [1, 2] >> len
  Run

  import nimpy let curses = pyImport("curses") var window = curses.initscr() window >> refresh()

  ERROR

  in expression 'window.refresh()': identifier expected, but found 'refresh()'

  First next time use code formatting, the error happens because a .() macro is involved here. Try using

   `obj`.`temp`()
  Run
