Subject: [PATCH 1/3] Add pattern matching support to Net::HTTPGenericRequest

Implements deconstruct_keys to enable pattern matching on HTTP requests
based on method, path, and other request attributes.

Example:
  case request
  in method: 'POST', path: %r{^/api/}
    handle_api_request(request)
  in method: 'GET', path: '/'
    handle_root
  end
