Thanks Eli! One thing I noticed when testing was that `package--builtins' was not populated on startup. According to the doc, the value is initialized when `finder-inf' is loaded. Locally I just use `(require 'finder-inf)' before using `package--builtins' as a workaround. Is there a better way? -- Regards, Xiyue Deng
