Invoke procs with brackets

You can invoke a <Proc (lambda)> with brackets Proc[]:

UriService = lambda do |username:, password:|
  def scream(n) n.upcase end

  "http://#{scream(username)}:#{password}@api.example.com"
end

UriService.call(username: "password", password: "123")
=> "http://PASSWORD:123@api.example.com"

UriService[username: "password", password: "123"]
=> "http://PASSWORD:123@api.example.com"
