I remember reading an article about a shorthand version, or extension, of HTML a few months ago. Its purpose was to make HTML code significantly more concise, by removing end tags, and it may have allowed loops of some sort as well. I want to use it now, but I can't seem to remember what it was called.
Searching online, I found Haml, but Haml syntax doesn't look like the example that I remember from the article. The syntax from the article made use of right angle brackets, which were a sort of replacement for indentation.
What is this language?
