You do it... but indirectly.  I wanted to add a quote to the value
already generated.  Like this:

  (equal #1='#1# ''#1#) ==> t

or

  (let ((x #1='#1#))
    (equal x `',x)) ==> t

The backquote-quote-unquote combination is a nicely short way of quoting
an existing value (instead of an expression like a symbol).

But the conclusion is the same as you described.
