Nim 语言是否有更短的对象初始化符号？

Question

type
  BinaryTree*[T] = ref object # BinaryTree is a generic type with
                              # generic param ``T``
    le, ri: BinaryTree[T]     # left and right subtrees; may be nil
    data: T                   # the data stored in a node

proc newNode*[T](data: T): BinaryTree[T] =
  # constructor for a node
  new(result)
  result.data = data

是否可以使用像

这样的单行快捷方式

proc newNode*[T](data: T): BinaryTree[T] = 
  data.new(data = data)

Answer 1

The tutorial says: "Note that referential data types will be nil at the start of the procedure, and thus may require manual initialisation" and here “要分配新的跟踪对象，必须使用 built-in 新过程 ”。但是如果你真的需要保存那一行，你可以做一个模板：

template aNewNode(data: untyped): void =
  new(result)
  result.data = data

proc newNode*[T](data: T): BinaryTree[T] =
  # constructor for a node
  aNewNode data

Does Nim language has shorter notation for object initialization?
