+ (description "When an undefined variable is dereferenced, it gets silently
+upgraded to an array or hash reference (depending of the type of the
+dereferencing). This behaviour is called autovivification and usually does
+what you mean but it may be unnatural or surprising because your variables get
+populated behind your back. This is especially true when several levels of
+dereferencing are involved, in which case all levels are vivified up to the
+last, or when it happens in intuitively read-only constructs like
address@hidden The pragma provided by this package lets you disable
+autovivification for some constructs and optionally throws a warning or an
+error when it would have happened.")
