Class Precedence List:

readtable,t

Description:

A readtable maps characters into syntax types for the Lisp reader; see Chapter 2 Syntax. A readtable also contains associations between macro characters and their reader macro functions, and records information about the case conversion rules to be used by the Lisp reader when parsing symbols.

Each simple character must be representable in the readtable. It is implementation-defined whether non-simple _characters_can have syntax descriptions in the readtable.
