built-in function to construct a map given a sequence of pairs

Question

when seq is called on a map, you get a list of pairs -

(seq {:a 4 :b 5}) 
;; => ([:a 4] [:b 5])

but when apply hashmap is called on the list, it does not give back the hashmap but uses the first pair as the key to the second

is there a built in function that returns a map when given a sequence of pairs?

You can use into:

(into {} (seq {:a 4 :b 5}))
;; => {:a 4 :b 5}
