syntax error: mixed named and unnamed parameters

语法错误"mixed named and unnamed parameters"通常发生在编程中，特别是那些使用命名参数风格的语言（如Python、JavaScript等），当函数或方法的调用中同时包含命名参数（使用名称指定参数值）和位置参数（按顺序提供参数值）时。在某些语言（例如JavaScript ES6或Python的默认参数模式）中，这可能是不允许的，因为它们期望一种一致性，要么所有的参数都由名称指定，要么都按照位置。
举个例子，在Python中，假设有一个函数定义如下：
def greet(name, greeting="Hello"):
print(greeting + ", " + name)

如果你试图像下面这样调用它，就会引发语法错误，因为混合了命名参数和位置参数：
greet("Alice", "Hi") // 这里会报错，因为第二个参数应该是按名称传递

正确的做法是全部使用名称或位置来调用：

只有位置参数：greet("Alice")
只有名称参数：greet(name="Alice", greeting="Hi")

在其他一些语言中，如JavaScript，这种错误可能会导致解析失败，因为它们更倾向于明确的参数形式。所以，在编写代码时，务必遵守特定语言的参数规定。

goalng mixed named and unnamed parameterssyntax

In Go, it is possible to mix named and unnamed parameters for a function or method. This allows for increased flexibility when calling functions, as well as the ability to specify default values for certain parameters.
Here is an example of a function with both named and unnamed parameters:
func exampleFunc(a int, b string, c ...int) {
// do something
}

In this example, a and b are named parameters, while c is an unnamed parameter. The ... before int indicates that c is a variadic parameter, meaning it can accept an arbitrary number of integers.
To call this function, you can pass in values for a and b using their names:
exampleFunc(a: 1, b: "hello")

You can also pass in values for a, b, and c without using their names:
exampleFunc(1, "hello", 2, 3, 4)

If you want to pass in values for a and c, but use the default value for b, you can use the name of the parameter you want to set:
exampleFunc(a: 1, c: []int{2, 3, 4})

This syntax allows for greater flexibility when calling functions in Go.
