Could you please make it optional? So that those who want the new
behaviour of (apply nil) can get it by doing something like:

    M-x customize-variable RET apply-nil-will-not-segfault-anymore RET

There are many users and third-party packages which depend on the old
behaviour. I'll show you stats in a minute...

Seriously: I remember one case when I tried to find CONSTANTLY or
similar but failed. I wrote some LAMBDA form. No big deal.
