PHP intl extension
Can you include the PHP intl extension in the kitchen-sink phpExtensionBundles for the playground?
Not sure if this is helpful but in our theme we are about to wrap the call to intl to check if the library exists as a workaround to get our theme working in playground.

Good luck with your blueprint :-)
Blueprint example to demonstrate calling the missing intl functions
GitHub keeps URI encoding additional characters in the example link, and Playground is not properly consuming it. Here's the link that works. Just copy and paste in the browser.

Or you can base64 encode the Blueprint in the URL:

And then it fits nicely into a markdown link.
