Array Programming Re-Imagined in Lisp
Ken Iverson's masterpiece reflected in the medium of Lisp.
April compiles a subset of the APL programming language into Common Lisp. Leveraging Lisp's powerful macros and numeric processing faculties, it brings APL's expressive potential to bear for Lisp developers. Replace hundreds of lines of number-crunching code with a single line of APL.
