You've been tricked by your local URL

I submitted the link that Julian posted (to his article) on X yesterday. There’s indeed some refresh action in my browser too, but the article opens up.

When it was first submitted the URL was http://0.0.0.0:4000/ .. that's since been magically fixed (by a mod?). I checked http://www.hydromatic.net and the post wasn't visible their either (most recent was Morel Rust release 0.2.0)

Interesting. I just posted the link from this X post [1] without modifying it (and it wasn’t 0.0.0.0…). I think one thing HN does is that when it detects a HTTP redirect, it will start using the referred to URL instead…

Yep.. it was the canonical header (not the fault of your submission, it's wrong on the blog and will effected SEO):

  <link rel="canonical" href="http://0.0.0.0:4000/draft-blog/2025/10/26/history-of-lambda-syntax.html" />

.. that the blog is called draft-blog doesn't help either.

PHP 5.3 in 2009 introduced anonymous functions. Arrow functions were introduced in 7.4 in 2019.
