cuando te enfrentas a un nuevo paradigma en programación agradeces un libro que te dé las claves, que te explique lo que no pone en el manual de referencia.
Más allá de la revisión de la sintaxis y de la combinación de sentencias, las explicaciones sobre el funcionamiento del runtime dan la respuesta a cómo construir herramientas y solucionar retos. ( )

let's just say: I read and studied the first edition at the University of Turin (phocopies, poor student); I bought the second edition (I will not bother to add it online); I bought the third edition... so, I liked the book, it seems!

Prolog har aldrig været mit favoritsprog, endsige på top 50 listen. Man har taget unification algoritmen og lavet et sprog udenom.
Ikke min kop te. Typografien i denne udgave er ikke specielt god, men om den så havde været 20 gange bedre, så havde det ikke reddet bogen. ( )
