Subject: Re: Change the default binding of C-x C-e ?

Message-ID: <m1JBZBV-002K4LC@rattlesnake.com> (raw)

    Things worked fine until I progressed in elisp to where I wanted
    to use defvar.

(info "(eintr)defvar")
says

       The `defvar' special form ... only sets the value of the
    variable if the variable does not already have a value.

I just checked this:  I can use C-x C-e (eval-last-sexp) to set the
value of a variable with `defvar' for the first time.  As described in
the Introduction, I cannot change the value a second time with
`defvar' and `eval-last-sexp'; for that, I must use `setq'.
