Archived tweet #9782 from the @leastfixedpoint Twitter Archive@elplatt SPKI SEXP sorta-kinda has ordered maps, in that maps end up being lists like (i-am-a-map (key1 value1) (key2 value2)); Bencode has niceish maps, with keys required to appear in lexicographic order, but the keys can't be anything but byte strings :-/
