SyntaxError: getter 和 setter 用于私有名称 #x，必须都为静态或都不为静态

SyntaxError: Identifier '#x' has already been declared (V8-based)
SyntaxError: getter and setter for private name #x should either be both static or non-static (Firefox)
SyntaxError: Cannot declare a private non-static getter if there is a static private setter with used name. (Safari)

相同名称的私有 getter 和 setter 必须都为 static 或都不为 static。此限制对公共方法不存在。

class Test {
  static set #foo(_) {}
  get #foo() {}
}

// SyntaxError: getter and setter for private name #foo should either be both static or non-static

由于 foo 是 私有的，因此方法必须都为 static

class Test {
  static set #foo(_) {}
  static get #foo() {}
}

或都不为静态

class Test {
  set #foo(_) {}
  get #foo() {}
}
