$ Client = Struct.new(:first_name, :last_name, keyword_init: true)
=> Client(keyword_init: true)

$ client_1 = Client.new(first_name: "Jamal", last_name: "Windsor")
=> #<struct Client first_name="Jamal", last_name="Windsor">

# using a getter
$ client_1.first_name
=> "Jamal"

# using a string as a key
$ client_1["first_name"]
=> "Jamal"

# using a symbol as a key
$ client_1[:first_name]
=> "Jamal"

# using an array index
$ client_1[0]
=> "Jamal"
