Common Lisp supports the concept of multiple values, [14] where any expression always has a single primary value, but it might also have any number of secondary values, which might be received and inspected by interested callers. This concept is distinct from returning a list value, as the secondary values are fully optional, and passed via a ...
The Common Lisp Object System (CLOS) is the facility for object-oriented programming in ANSI Common Lisp. CLOS is a powerful dynamic object system which differs radically from the OOP facilities found in more static languages such as C++ or Java. CLOS was inspired by earlier Lisp object systems such as MIT Flavors and CommonLoops, although it ...
Lists are typically implemented either as linked lists (either singly or doubly linked) or as arrays, usually variable length or dynamic arrays.. The standard way of implementing lists, originating with the programming language Lisp, is to have each element of the list contain both its value and a pointer indicating the location of the next element in the list.
There are other common notational differences as well; for example Apply is often called Eval, [6] even though in computer science, these are not the same thing, with eval distinguished from Apply, as being the evaluation of the quoted string form of a function with its arguments, rather than the application of a function to some arguments.
This is sometimes known as the "Lisp-1 vs. Lisp-2" distinction, referring to the unified namespace of Scheme and the separate namespaces of Common Lisp. [23] In Scheme, the same primitives that are used to manipulate and bind data can be used to bind procedures. There is no equivalent of Common Lisp's defun and #' primitives.
Common Lisp provides a feature called dynamically scoped variables. Dynamic variables have a binding which is private to the invocation of a function and all of the children called by that function. This abstraction naturally maps to thread-specific storage, and Lisp implementations that provide threads do this.
Common Lisp; Compiled Native Interface (CNI), alternative to JNI used in the GNU compiler environment. One of the bases of the Component Object Model is a common interface format, which natively uses the same types as Visual Basic for strings and arrays. D does it the same way as C++ does, with extern "C" through extern (C++)
In a programming language, an evaluation strategy is a set of rules for evaluating expressions. [1] The term is often used to refer to the more specific notion of a parameter-passing strategy [2] that defines the kind of value that is passed to the function for each parameter (the binding strategy) [3] and whether to evaluate the parameters of a function call, and if so in what order (the ...
