Merges not working as expected

[torrance]

I have the following yaml configuration:

default: &default
  user: "adm"
  file_perms: "664"

folders:
  - path: "/var"
    user: "www-data"
    dir_perms: "775"

  - path: "/var/site/"
    group: "www-editors"

  - <<: *default
    path: "/lib/folder2"

And I'm expected to be able to merge the key values for 'default' into the third folders list item.

My struct that I'm providing to the Unmarshal method looks like:

type config struct {
    Folders []*folder
}

type folder struct {
    Path      string
    User      string
    Uid       int
    Group     string
    Gid       int
    DirPerms  string `yaml:"dir_perms"`
    DirMode   os.FileMode
    FilePerms string `yaml:"file_perms"`
    FileMode  os.FileMode
    Children  folders
}

Note there's no 'default' key provided as I don't care about loading the default value, but I still would expect its keys to be merged into the folders list.

Am I doing something wrong, or does go-yaml not handle merges?

That doesn't yet work indeed, but it should. Here is the documentation reference:
