Of course there is. And if you don't like the name `pushnew`, for
example because it starts with the distateful "p", you can use
`cl-pushnew`, which also has the advantage of not being deprecated.

You mean, do the same as `pushnew`? Yes, of course.
You could also define a function or even a macro that does that
for you. A good name for it could `my-pushnew` ;-)
