yamljsonmap
A type to facilitate interoperability between yaml and json Marshaling and Unmarshaling.
When using go-yaml, unmarshalling yaml will result in
map[interface{}]interface{} types. However, json.Marshal cannot marshal map[interface{}]interface{}.
This makes interoperability between the gopkg.in/yaml.v2 and encoding/json libraries problematic.
Solutions
One approach taken by github.com/ghodss/yaml is to convert Yaml to Json, and then Marshal from Json. However, with this approach you lose field ordering in a struct.
This approach adds a new type yamljsonmap.StringKeyMap which can be used in place of a map. It automatically converts
map keys to strings when marshalling json and unmarshalling yaml.
