I expected this to work:
(into {} (partition 2 (split (slurp "data") #",")))
But unfortunately, `into' doesn't seem to allow pushing lists of pairs
into a map. But vectors are allowed:
(into {} (map vec (partition 2 (split (slurp "data") #","))))
Can somebody explain why vectors are allowed and lists not?
