Alexandria is a project and a library. As a project Alexandria’s goal is to reduce duplication of effort and improve portability of Common Lisp code according to its own idiosyncratic and rather conservative aesthetic. As a library Alexandria is one of the means by which the project strives for its goals.

Practically speaking, lists  hyphen-delimited, in the style of Lisp. For example, the Likewise, the proof of the mappend-assoc law for Maybe a depends on the law also holding for a.

Las funciones en LISP se pueden crear y llamar, como ya hemos visto, pero tambien se pueden manipular como cualquier otro tipo de objeto. Ya hemos visto un ejemplo de programación high-order: mapcar. (defun mappend (fn lista) "Aplica fn a todos los elementos de lista y hace un append de los resultados" (apply #'append (mapcar fn lista))) A Straightforward Solution. We now want to develop a short Lisp program that generates random sentences from a phrase-structure grammar. The most straightforward approach is to represent each grammar rule by a seperate Lisp function.
