"curses" gem needs to be updated, I emailed Shugo about it a few
weeks ago but no response.  See attached patch.
(I don't use JavaScript or agree to GitHub Terms of Service).

For C extensions, I recommend just deprecating with a
compile-time warning in C, NOT runtime.  Regular Ruby users
installing C ext gems may not be able to do anything about it.
