Yeah, the $$ blocks and $ ... $ inlines are very common and everybody knows them (not speaking that almost every matured static site generator supports them in some way). Perhaps we should consider hooking Lua on specific AST nodes and that way
we can have both ways at once (the Lua call ${math.inline[[ ... ]]} and the common syntax). @MrMugame Is it doable (to hook Lua on math AST nodes)?
