libautovivification-perl - 0.18-1+b1 main

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.
