--- title: "A late April 1st proposal for Ruby?" publication: "Ruby Weekly" issue: 621 published_at: "2022-09-22" canonical_url: "https://rubyweekly.com/issues/621" --- Plus Haml 6.0, bye to Subversion, points against RSpec, and the Rails 6 to 7 upgrade process. | #​621 — September 22, 2022 [Read on the Web](https://rubyweekly.com/issues/621) Ruby Weekly [![\](https://res.cloudinary.com/cpress/image/upload/w_1280,e_sharpen:60,q_auto/gbe01zlt49tzgnaxptc1.jpg)](https://bugs.ruby-lang.org/issues/19015) [Proposal: Extending HereDocs to Support Multiple Languages?](https://bugs.ruby-lang.org/issues/19015) — To set the scene here, Matz’s [initial reaction](https://twitter.com/yukihiro_matz/status/1572880270013124608) to this proposal was _“There’s still half a year left until April Fool’s Day.”_ The idea here is to be able to specify a format/language against heredocs (somewhat as with Markdown code blocks) and to then process those documents dynamically in a custom method. Joke or not, when such an esteemed core team member has an idea, it’s worth checking out, and plenty of jokes have taken off (SOAP..
