How do I do _THIS_ with emacsclient?

Hi, I have the following problem: I try using something
like
$ --eval "(ediff-files (pop
command-line-args-left) 
  (pop command-line-args-left))" "file1"
"file2"

and when $ is equal to emacsclient, this fails
pretty badly:
command-line-args-left is nil, and Emacs tried to execute
file1 and
file2, leading to undefined variable complaints.

This behavior clearly is dissatisfactory.  Any idea what I
could write
to have this more or less work with emacsclient without
breaking when
using Emacs?

I don't know what to do about the argmunents not available
with
`command-line-args-left' but why not use a simpler command
like:
    $ --eval '(ediff-files "file1"
"file2")'

Because file1 and file2 may not be properly quoted for use
in Lisp
strings.

Is it a real problem or a principal one ?
For real life you can always do:
    ln -s "file1" /tmp/file1_$$
    ln -s "file2" /tmp/file2_$$
    $ --eval '(ediff-files
"'/tmp/file1_$$'" "'/tmp/file2_$$'")'
    rm -f /tmp/file1_$$ /tmp/file2_$$

Ehud.
