a list which can be used in place of a function name in
certain contexts to denote a function by directly describing its
behavior rather than indirectly by referring to the name of an
establishedfunction; its name derives from the fact that its
first element is the symbollambda.
n. a running instantiation of a Common Lispimplementation.
A Lisp image is characterized by a single address space in which any
object can directly refer to any another in conformance with this specification,
and by a single, common, global environment.
(External operating systems sometimes call this a
or "process." Note however, that the issue of a "process" in such
an operating system is technically orthogonal to the issue of a Lisp image
being defined here. Depending on the operating system, a single "process"
might have multiple Lisp images, and multiple "processes" might reside
in a single Lisp image. Hence, it is the idea of a fully shared address
space for direct reference among all objects which is the defining
characteristic. Note, too, that two "processes" which have a communication
area that permits the sharing of some but not all objects are considered
to be distinct Lisp images.)
adj. (of an object)
referenced directly in a program rather than being computed by the program;
appearing as data in a quoteform,
or, if the object is a self-evaluating object,
appearing as unquoted data.
In the form (cons "one" '("two")),
the expressions "one", ("two"), and "two"
are literal objects.
