pragma for lexically disabling autovivification
autovivication is a Perl pragma that enables developers to control whether variables can be created automatically on their first use, rather than requiring them to be defined beforehand. While occasionally useful, this behaviour can result in subtle bugs that are difficult to debug.
This pragma lets you disable autovivification for some constructs and can optionally also emit a warning or error when it would have happened.
