a readtable.

A readtable that conforms to the description of Common Lisp syntax in Chapter 2 (Syntax).

The value of *readtable* is called the current readtable. It controls the parsing behavior of the Lisp reader, and can also influence the Lisp printer (e.g., see the function readtable-case).

(readtablep *readtable*) → true 
(setq zvar 123) → 123 
(set-syntax-from-char #\z #\' (setq table2 (copy-readtable))) → T 
zvar → 123 
(setq *readtable* table2) → #<READTABLE> 
zvar → VAR 
(setq *readtable* (copy-readtable nil)) → #<READTABLE> 
zvar → 123
