If you don't know, you can always just ask the language :)

false
But, I agree; the seq/coll distinction can be very confusing at first,
especially when faced with seemingly contradictory outputs like
user> (= '(1) [1])
true
user> (= '() [])
false
user> {'(1) true}
{(1) true}
user> (get *1 [1])
true
user> (hash-map '(1) true)
{(1) true}
user> (get *1 [1])
nil
