The curly-brace syntax is almost always preferable. Keep in mind that the
linebreaks are separated into their own elements (For more on this behavior see
[1].) So this markup:
◊ol{The remaining forty-nine stalks ◊(comment "" ",") two piles.
another item
another item
}
Produces this list of five (not three) elements:
'("The remaining forty-nine stalks "
(comment "" ",")
" two piles."
"\n"
"another item"
"\n"
"another item")
Probably what you want is to preprocess `elements` into bigger chunks
representing list items before passing each to your 'li tag lambda. For
instance this:
(require sugar/list)
(filter-split '("The remaining forty-nine stalks "
(comment "" ",")
" two piles."
"\n"
"another item"
"\n"
"another item")
(λ (e) (equal? e "\n")))
Produces these sublists:
'(("The remaining forty-nine stalks " (comment "" ",") " two piles.")
("another item")
("another item"))
For a more elaborate example of list-item detection, see the
`detect-list-items` function [2] in the pollen-tfl sample project.
