Re-open *scratch* buffer in Emacs?

Question

If I accidentally closed the scratch buffer in Emacs, how do I create a new scratch buffer?

Answer 1

I used to use dwj's solution, and I was quite happy about it, until the day I realized that it failed when you actually rename the scratch buffer (for example by saving it).

Then I adopted this, which works well for me :

  (run-with-idle-timer 1 t
    '(lambda () (get-buffer-create "*scratch*")))
