Is this idea doable? How hard would it be to implement? [Reference discussion](https://community.silverbullet.md/t/mathematical-expressions/421/20).

It would be great if we could hook in, say, `[[link]]`s and then write on-hover preview of the linked page in Lua or do other insane things like that. 😃

Sidenote: For me it would be great if I could do what’s mentioned in the referenced discussion: to make hook in `$ ... $`'s AST node to use @MrMugame’s `${latex.inline(...)}` and similarly to hook in `$$ ... $$`'s AST node for the `${latex.block(...)}`.
