Note that this library created for specific cases with simple scalar values manipulation.
If you need more complex ast manipulation check this libs:

• tailscale/hujson
• creachadair/tomledit
• goccy/go-yaml

If you need to just marshal/unmarshal formats to go data structures check this:

• stdlib encoding/json
• pelletier/go-toml
• goccy/go-yaml
