sets & maps make no guarantee about the order of their entries. In fact,
they deliberately use hash functions to keep simple keys like 1,2,3 "spread
out" in their hash-codes. This causes the "random" ordering when printed.
If you want a set to print in order (often worth the trouble, I think), use
"sorted-set":
user=> (def s1 (set [1 2 3]))
#'user/s1
user=> s1
#{1 3 2}
user=> (def s2 (into (sorted-set) s1))
#'user/s2
user=> s2
#{1 2 3}
The same trick works for "sorted-map"
