a readtable.
A readtable that conforms to the description of Common Lisp syntax in 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
