Message-ID: <tifr7h$952$1@ciao.gmane.io> (raw)

The documentation for push is

> push is a Lisp macro in ‘subr.el’.
> 
> (push NEWELT PLACE)
> 
> Add NEWELT to the list stored in the generalized variable PLACE.
> This is morally equivalent to (setf PLACE (cons NEWELT PLACE)),
> except that PLACE is evaluated only once (after NEWELT).
> 
>   Other relevant functions are documented in the list group.
>   Probably introduced at or before Emacs version 21.1.
