What is wrong with initializing structures without named fields (positional initialization)?

Positional initialization of structs in Go (without specifying field names) has several disadvantages:

• Vulnerability to errors when changing the order of fields: if the order of fields in the struct changes, positional initialization can lead to incorrect value assignment.
• Poor readability: without field names, it's hard to understand which value corresponds to which, especially if the struct is large.
• Difficulties when adding new fields: adding new fields to the struct requires adjusting all places with positional initialization.

Therefore, it is recommended to use named initialization, for example:

type Person struct {
    Name string
    Age  int
}

p := Person{Name: "Alice", Age: 30} // clear and safe

Unlike:

p := Person{"Alice", 30} // positional initialization, less safe
