Glad to see your comment. Not sure I get you right. I also do not like many data notations and formats floating around. I hope there's one notation that can unify all the data that I'm concerned with. That's why I created Mark.

Sorry for writing in a strange way, in short, your Mark is wonderful, but I don't like the symbols in the markup like "<" before each command, because without them, in fact, you can also make a working markup, maybe they use it for beauty?

As for the '<' and '>' to open and close an element, there are two potential kinds of syntax design. Option 1 is to use some explicit delimiters. Mark 1.0 has settled on '<' and '>'. Mark 0.11 was using '{' and '}', which I felt confusing with map. So I changed to '<' and '>', to make it consistent with HTML/JSX and XML, which most developers are already used to. Option 2 is to use indentation to delimit the enclosed child content, like in Python and YAML.

Option 2 looks cleaner for configuration kind of usage. However, Mark is designed to be embedded in a scripting language, and used beyond just configuration files. Unless the scripting language uses indentation as delimiter, like Python, option 2 will not work.

Personally, I prefer C/Java/JS family of languages that has insignificant whitespace. So Mark is designed to use explicit delimiters '<' and '>' to enclose an element.

Hope that explains one of the most important syntax designs of Mark.
