TICL : a Type Inference System for Common Lisp | Most current Common Lisp compilers generate more efficient code when supplied with data type information. However, in keeping with standard Lisp programming style, most programmers are reluctant to provide type information; they simply allow the run-time type system to manage the data types accordin... | compilers; LISP; type interface; TICL | 1989-03 |
