This variable holds a list of expressions that are safe to
evaluate when found in the @samp{Eval:} ``variable'' in a file
local variables list.
@end defopt
If the expression is a function call and the function has a
@code{safe-local-eval-function} 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.
