Subject: [PATCH 1/4] inboxwritable: mime_from_path: reduce `$/' scope and returns
Date: Sat,  1 Aug 2020 08:12:24 +0000
Message-ID: <20200801081227.21412-2-e@yhbt.net> (raw)
In-Reply-To: <20200801081227.21412-1-e@yhbt.net>

We don't want `local $/' affecting Eml->new, and we can
use implicit returns which may be faster on older Perl.
