A generalized variable or place form is one of the many places in Lisp memory where values can be stored. The simplest place form is a regular Lisp variable. But the CARs and CDRs of lists, elements of arrays, properties of symbols, and many other locations are also places where Lisp values are stored. For basic information, see Generalized Variables in GNU Emacs Lisp Reference Manual. This package provides several additional features related to generalized variables.
