Using the trailing ``` has a ugly drawback: we have to read all the code block before being able to colorize it. Gemini has a really nice property of needing only the first few bytes of each line to decide its "type", there's no going back and forward like it is for markdown (where link references can be declared after the link itself) or HTML. This allows a really cool property: text/gemini files can be *streamed* on the fly and easily parsed on the fly. For instance: a irc-like application can have a page that never stop loading where all the message "appear" as soon as someone sends them, and a second page where the users can send text. That said, regarding the try-and-report part, if someone really wants to see how this could work, I suggest try hacking something on top of elpher: Emacs is really cool for this kind of things and already has syntax highlighting for various programming languages.
