+local variables list.
address@hidden defopt

+  If the expression is a function call and the function has a
address@hidden property, the property value
+determines whether the expression is safe to evaluate.  The property
+value can be a predicate to call to test the expression, a list of
+such predicates (it's safe if any predicate succeeds), or @code{t}
+(always safe provided the arguments are constant).

   Text properties are also potential loopholes, since their values
 could include functions to call.  So Emacs discards all text
 properties from string values specified for file local variables.
