user=> {"0" 0 "1" 1 "2" 2 "3" 3 "4" 4 "5" 5 "6" 6 "7" 7 "8" 8 "9" 9 "10" 10
"11" 11 "12" 12 "13" 13 "14" 14 "15" 15}
{"11" 11, "12" 12, "13" 13, "14" 14, "15" 15, "0" 0, "1" 1, "2" 2, "3" 3,
"4" 4, "5" 5, "6" 6, "7" 7, "8" 8, "9" 9, "10" 10}
nor the insertion order:
user=> (into {} (for [i (range 16)] [(str i) i]))
{"11" 11, "12" 12, "13" 13, "14" 14, "15" 15, "0" 0, "1" 1, "2" 2, "3" 3,
"4" 4, "5" 5, "6" 6, "7" 7, "8" 8, "9" 9, "10" 10}
but the order should be stable for a given set of keys.
BUT if your map is small enough it may be an arraymap: definition/insertion
order will be preserved.
