This thread is speculating on ways to improve the parsing behaviour of the system. There’s certainly scope for improvements, but I think you'd really need to understand the code itself in order to understand the impact of changes you’re exploring. Working with a metaphorical description of how the parser works won’t be sufficient to make meaningful proposals. Anyhow, the wikitext parser is pretty simple. Each “parse rule” requires it to look out for a certain pattern; for example, the pattern for the start of a widget might be `<$`. When the parser spots such a pattern it then checks the following characters to see if they match the full rule. For widgets, that means that it looks for the widget name, optional attributes and the closing `>`. It looks for the attributes without regard for the content of the attribute strings; it’s just looking for a sequence of letters/digits, an equals signs, an opening quote, the attribute content, and a closing quote. It’s only later that the content of the attribute might be parsed as a filter.
