平衡点

_ Emacs30 で lookup-el が動かなくなった.

make-verctor → obarray-make という奴ですね.

• What's New in Emacs 30.1? - Mastering Emacs

Old code which (incorrectly) created "obarrays" as Lisp vectors filled with something other than 0, as in '(make-vector N nil)', will no longer work, and should be rewritten to use 'obarray-make'. Alternatively, you can fill the vector with 0.

とりあえず

 (defsubst lookup-intern-string (string)

としたら動くようにはなったけど, これでエエのかしらね…

でもって, 現在の lookup-el の upstream はどこなの？
