I hate the status quo of the html template engine. They are not portable at all. No winner, not even most popular, that means no consensus. We should be able to unlock platform locked-in and be able to move/reuse templates around Shopify, Wordpress, Webflow, whatever platform/framework that can fill dynamic data into html template. Javascript based templates are the worst for portability. ELisp seems like going to the right direction but I'd like to hear more about logic-ful or logic-less, what should only be allowed in template, how context-free it is, etc. ps; as someone who hate parsing stuff with passion. give me a format that's good enough for hand authoring programmable format. S-expression is close .. but not yet a great solution.
