For the record, I would prefer YAML or TOML of all formats...
Format used by DUB should be something made for humans. No matter how I like
or dislike JSON, it is not made for humans. - It is made to be easy to
parse. YAML and TOML (https://github.com/toml-lang/toml) were made for
humans and IMHO they should be used for these purposes.
