Ausführliche Beschreibung | 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 (e.g.
when you store a value) but it's sometimes unnatural or surprising because
your variables gets 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 exists.
.
This pragma lets you disable autovivification for some constructs and
optionally throws a warning or an error when it would have happened.
