Is there a reason not to make ordinary `get' safe?  That would be
simpler for Lisp programmers than introducing safe-get.
The code would be simpler, the manual would be simpler, even
etc/NEWS would be simpler.

Agreed.  Same thing for safe-plist-get.
BTW, XEmacs has overloaded `get' so that when applied to an overlay it does
overlay-get, ...

Not really, except
a) it will not catch errors in the symbol plist.
b) it is slightly slower

I will revert my changes, and just make get safe...

But then, why don't we make plist-get safe
and get rid of safe-plist-get, too ?

IIRC, safe-plist-get is new in 22.1, so I don't see any big
problems doing that...

That's not a drawback.

    b) it is slightly slower

That's a slight drawback, but probably not significant.

Good.

    But then, why don't we make plist-get safe
    and get rid of safe-plist-get, too ?

Yes, we may as well.

I see no possible harm in that, so we may as well be compatible.
