[[info:elisp#Some Terms]] [...] that convert textual representations of Lisp objects into actual Lisp objects, and vice versa. [[info:elisp#Lisp Data Types]] Objects of the same type have similar structures and may usually be used in the same contexts. [...] the primitive type of each object is implicit in the object itself. [...] Such type declarations do not exist in Emacs Lisp. A Lisp variable can have any type of value, and it remembers whatever value you store in it, type and all. I would have phrased it differently. =E2=80=9CThe representation of a Lisp program is fundamental. At a high lev= el, the operation of the program is represented by its components. At a low level, a Lisp program is a collection of routines which process data found in the source files. Globally, a Lisp program is a set of expressions formed with objects: data structures, lists and symbols.=E2=80= =9D
