Hi Matthew,
The catch is that there's a bunch of other stuff in the `Block`.
That is, the special token is some substring of `s`
f :: Block -> Block
f (CodeBlock _ s) = RawBlock (Format "latex") ("\\MySpecialToken{" ++ s ++
"}")
f b = b
and I don't want to lose that. So I can write a function
f :: Block -> [Block]
where each CodeBlock is expanded into a list of :
`RawBlock (Format "latex")` of the kind above,
and the remaining, unchanged CodeBlock
But that causes problems with toJSONFilter as I can't pass in a
transformation of the form
[Block] -> [Block]
Because there is no instance of Walkable for [Block] ... :(
