Tijs van der Storm discusses object algebras as a solution to the expression problem – the inability to extend functional programming languages.
Giovanni Asproni suggests that teams should not blindly embrace a methodology but rather create their own suiting their specific needs by using an approach based on patterns and pattern languages.
Philip Wadler presents a practical theory of language-integrated query based on quotation and normalization of quoted terms and a theorem guaranteeing that a host query generates a single SQL query.
