Subject: [PATCH 01/43] gzipfilter: minor cleanups
Date: Sun, 5 Jul 2020 23:27:17 +0000 [thread overview]
Message-ID: <20200705232759.3161-2-e@yhbt.net> (raw)
In-Reply-To: <20200705232759.3161-1-e@yhbt.net>
We currently don't use bytes::length in ->write, so there's no
need to `use bytes'. Favor `//=' to describe the intent of the
conditional assignment since the C::R::Z::Deflate object is
always truthy. Also use the local $gz variable to avoid
unnecessary {gz} hash lookups.
