Variable in a dotted list

[Peter Dyballa]

Hello!

How can I create a dotted list with the value of a variable as cdr?  
The documentation is

 -- Variable: backup-directory-alist
     This variable's value is an alist of filename patterns and backup
     directory names.  Each element looks like
          (REGEXP . DIRECTORY)

and the value of DIRECTORY is a concat-enation of user-emacs-directory  
and a "name." It works to use

        (setq backup-directory-alist   '(("." . "~/.emacs.d/Name")))

but it's a bit too inflexible IMO...
