Subject: [PATCH 7/7] view: avoid intermediate array when streaming thread
Date: Thu,  4 Aug 2022 08:17:03 +0000	[thread overview]
Message-ID: <20220804081703.1410595-8-e@80x24.org> (raw)
In-Reply-To: <20220804081703.1410595-1-e@80x24.org>

We can rely on auto-vivification to avoid an intermediate
array for the map result.
