From Matz<p>>Prism needs quality and for that it needs to be experimented with on a wider scale. For that reason, I agree with making Prism the default in previews (when Prism passes all tests). Whether it will eventually become the default in 3.4 depends on quality.<p>Once it land on master. It will automatically be tested on Github and 37Signals, in addition to Shopify. I remember there were one or two other companies that run on Ruby / Rails master as well. Cookpad? or was it Discourse.<p>If we could get Gitlab and Stripe to test against it, and perhaps a few other Ruby shops that doesn't use Rails as representatives then I think Prism is damn well tested.<p>Wondering what else is baking in Ruby 3.4. YJIT team has been very quiet....
