This is a really interesting exploration of an idea for a more concise ERb alternative by Kasper Timm Hansen. HAML and Slim have never felt appealing to me because they feel like they blur the lines between markup and back-end code, but a less-verbose approach to ERb sounds fantastic.
ERB tags
<% %>and<%= %>feel so noisy, having to add%>a Ruby line feels as if I’d had to write;to end my Ruby lines. So what if we had a simpler syntax that can figure out how to auto-close for us.
Even if it never goes anywhere or sees wide adoption, just seeing this kind of exploration and experimentation with fun ideas to make the Ruby ecosystem even more pleasant is exciting and encouraging.
