Subject: | Quoting keys with spaces is incompatible with older YAML::Tiny |
If you encode a structure that uses a key with a space in it, YAML::Tiny always quotes the key. This is incompatible with older YAML::Tiny versions. This means that a META.yml produced on a newer perl will be unparseable on older versions.
For most keys with spaces, the quoting is unnecessary. We should be able to do better.
The change to quote keys with spaces was 73ea4027cf311eda41d7aff103affdd766699782. The change allowing reading quoted keys was 9b62a3ade41ca103672a8538ac238f8758958bbe.
