(hash-set ...) is equivalent to #{...}

'set' takes a single collection as an argument, which it will treat as
a seq and pour into a hash-set, so above the string behaves as a seq
of chars, and each char becomes an item in the set:

user=> (set "aeiou")
#{\a \e \i \o \u}

On the other hand, hash-set and #{} expect several args, each of which
becomes an item in the set:

user=> (hash-set "aeiou")
#{"aeiou"}
