Yeah, definitely some tradeoffs there. I do like that it makes the common use cases easy. And yeah, I did make quite the "turduckin" as you put it .

A more concrete criticism: suppose you wanted to embed some markdown, where all of the content consisted of an indented code block.

%markdown: a code block

    fn foo(){

        # do stuff

    }

%%

My understanding is the leading spaces would be removed, breaking the formatting and making it normal text instead of a code block.
