package main

import (
	"fmt"
	"github.com/goccy/go-yaml"
)

func main() {
	tests := []struct {
		value interface{}
	}{
		{
			value: struct {
				A []string `yaml:"a"`
			}{
				A: []string(nil),
			},
		},
		{
			value: struct {
				A []string `yaml:"a"`
			}{
				A: []string{},
			},
		},
	}
	
	for _, tt := range tests {
		d, _ := yaml.Marshal(tt.value)
		fmt.Printf("%s", string(d))
	}
}

before:
