I wrote in a different response to the original email: > Working to have a vote on https://github.com/php/php-src/pull/4886 might be a > good first step, and something I was personally interested in seeing in > 8.0-dev. I thought I mentioned that there was a PR that implemented is_list() in another email in that thread, but it turns out I was mistaken - I just mentioned the URL. Sorry. That PR "Add is_list function" (https://github.com/php/php-src/pull/4886) copies the is_list implementation that the JSON extension uses internally for efficient serialization of lists. I'm glad to see the interest in support for is_list(), list types, or working on potential implementations.
