    # `def method = attributes[:method]` overrides Kernel#method to expose the
    # Dry::Struct attribute. Since :method is a required (non-optional) attribute,
    # it is always present in `attributes`, making Hash#[] and Hash#fetch
    # identical in practice. self[:method] is also equivalent because
    # Dry::Struct#[] delegates to attributes.fetch. No test can distinguish
    # these forms because constructing a Request without :method is impossible.

    # `responses.map(&:to_response)` and `self.map(&:to_response)` are
    # equivalent because BatchResponse#each delegates to responses.each.
    # Enumerable#map iterates via each, so both forms call to_response on
    # the same objects in the same order. No test can distinguish them.
