Would it be possible to unreserve the `@` character in YAML 1.3? #286

Open anatoly-scherbakov opened 2 years ago

anatoly-scherbakov commented 2 years ago

YAML-LD initiative, looking forward to express JSON-LD vocabulary in YAML, forces to write something like this:

"@context": https://example.org/context.json
"@type": example:Page

The @-keywords have to be quoted because the @ character is reserved.

Is there any plan to perhaps unreserve that character? Or perhaps there are particular plans how to use it? Thank you!

There are no plans to just unreserve that character. It might get used in the future as a prefix for something like function calls. We only have two reserved chars, they are too precious to just unreserve them :)

While it's understandable to reserve such characters for future needs, it's crucial to recognize the potential of @ as a versatile and potentially language-independent annotation mechanism for both metadata and functions. It's also just too valuable leave it untouched without a clear plan for its use.
