GitHub - phantomics/april: The APL programming language (a subset thereof) compiling to Common Lisp.

APL veritably hums with algorithmic power. As a handful of characters run past the lexer, vast fields of data grow, morph and distil to reveal their secrets. However, APL has hitherto dwelt in an ivory tower, secluded inside monolithic runtime environments. If you have a store of data you'd like to process with APL, getting it there can be an ordeal akin to hauling tons of cargo on donkeys' backs
