9.4 Symbol Properties

A symbol may possess any number of symbol properties, which can be used to record miscellaneous information about the symbol. For example, when a symbol has a risky-local-variable property with a non-nil value, that means the variable which the symbol names is a risky file-local variable (see File Local Variables).

Each symbol’s properties and property values are stored in the symbol’s property list cell (see Symbol Components), in the form of a property list (see Property Lists).
