Its a big shame, as my preference for how to see code would 100% fall in a "literate style" if I could get it. I'd love an even more dynamic view than that style, if I could. But, I'm fairly sure that 100% correct syntax highlighting would not be possible in that world? Especially in some of the more complicated syntax options out there.

I'm also curious on how many times you have used something that didn't get syntax highlighting correct? Even using some of the more advanced cweb features of org-mode, it typically gets things more correct than not. And I don't think it is using anything more than regexps? (I have not checked to see how the tree sitter stuff interacts with cweb in many blocks. Will try and look into that.)
