This is an open question. Fennel may support this officially in the future. For the moment, what I can implement could be
;;;; In a module
;; | This style? `|` could be the other character.
(local value-a true)
(local value-b
{:fnldoc/docstring "Is this possible?"}
true)
{: value}
## `value-a`
This style? `|` could be the other character.
## `value-b`
Is this possible?
