Ref: https://github.com/ruby/json/pull/718 The existing `Parser` interface is pretty bad, as it forces to instantiate a new instance for each document. Instead it's preferable to only take the config and do all the initialization needed, and then keep the parsing state on the stack on in ephemeral memory. This refactor makes the `JSON::Coder` pull request much easier to implement in a performant way. https://github.com/ruby/json/commit/c8d5236a92 Co-Authored-By: Étienne Barrié <etienne.barrie@gmail.com>
