Subject: closure within closure, incorrect (?) byte-compiler warnings
Date: Mon, 01 Nov 2021 08:06:44 +0100 [thread overview]
Message-ID: <87o874tkvv.fsf@zoho.eu> (raw)
See the code, it is a closure (actually two) with the
intention of keeping inside a closure with the intention
of sharing ...
Keep and share! Good intensions that also seem to work, only
the byte-compiler reports incorrect/unhelpful warnings what
I can see.
Also note the inconsistent byte-compiler formating, both
`next' and ‘next’ ...
