The rule expresses the opinion that the argued flexibility and extensibility designed into the programming language Lisp includes all functionality that is theoretically needed to write any complex computer program, and that the features required to develop and manage such complexity in other programming languages are equivalent to some subset of the methods used in Lisp.
CLOS does not by default support dispatch over all Common Lisp data types (for example dispatch does not work for fully specialized array types or for types introduced by deftype). However, most Common Lisp implementations provide a metaobject protocol which allows generic functions to provide application specific specialization and dispatch rules.
ECL includes a bytecode interpreter and compiler. It can also compile Lisp code to machine code via a C compiler. ECL then compiles Lisp code to C, compiles the C code with a C compiler and can then load the resulting machine code. It is also possible to embed ECL in C programs, and C code into Common Lisp programs. GNU Common Lisp (GCL)
However, unlike C preprocessor macros, the macros are Lisp functions and so can exploit the full power of Lisp. Further, because Lisp code has the same structure as lists, macros can be built with any of the list-processing functions in the language. In short, anything that Lisp can do to a data structure, Lisp macros can do to code.
In the early development of Lisp, association lists were used to resolve references to free variables in procedures. [ 5 ] [ 6 ] In this application, it is convenient to augment association lists with an additional operation, that reverses the addition of a key–value pair without scanning the list for other copies of the same key.
In the C programming language, operations can be performed on a bit level using bitwise operators. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits ...
Statically and dynamically scoped Lisp dialect developed by a loose formation of industrial and academic Lisp users and developers across Europe; the standardizers intended to create a new Lisp "less encumbered by the past" (compared to Common Lisp), and not so minimalist as Scheme, and to integrate the object-oriented programming paradigm well ...
Kyoto Common Lisp (KCL) is an implementation of Common Lisp by Taichi Yuasa and Masami Hagiya, written in C to run under Unix-like operating systems. KCL is compiled to ANSI C . It conforms to Common Lisp as described in the 1984 first edition of Guy Steele 's book Common Lisp the Language and is available under a licence agreement.
