News & Updates

3/19/2015

Add symbols for anaphoric macro internals, IT, THIS, and SELF to package exports for better end-user experience. Will be available in April 2015 release of Quicklisp.

8/14/2014

Issue with incompatible change to backquote syntax in SBCL 1.2.2 resolved; tested against and builds on SBCL 1.2.0-1 and 1.2.2. Will be available in the August release of Quicklisp.

12/18/2013

Now available in the December 2013 distribution of Quicklisp

Usage

Make sure you have the latest Quicklisp distribution, then include it as a dependency in your system definition, or from the REPL evaluate (ql:quickload "let-over-lambda").

(ql:quickload "let-over-lambda")
(lol:flatten '((A . B) (C . D) (E . (F G H (I . J) . K))))
=> (A B C D E F G H I J K)

LET-OVER-LAMBDA now uses the named-readtables library instead of modifying the global readtable. To use LOL reader macros in your Lisp source files, you will have to add both let-over-lambda and named-readtables to your project dependencies, and the following line after your call to in-package, in every source file you wish to use LOL syntax:

(named-readtables:in-readtable lol:lol-syntax)
