Subject: [PATCH] lei: always use 3-arg open perlop
Date: Mon, 22 Nov 2021 18:38:09 +0000	[thread overview]
Message-ID: <20211122183809.216219-1-e@80x24.org> (raw)

Future-proofing in case future versions of Perl warn on this, since
2-arg forms of open may be subject to injection vulnerabilities
with non-literal args.
