bug#46909: 27.1; (rx (literal EXPR))

[Drew Adams]

 (elisp) 'Rx Constructs' has this:

'(literal EXPR)'
     Match the literal string that is the result from evaluating the
     Lisp expression EXPR.  The evaluation takes place at call time, in
     the current lexical environment.

But where can that construct be used?  I tried `(rx (literal "abc"))'
(and other EXPRs), and I just get an error saying that `literal' isn't
recognized for RX.  Doc bug?  Code bug?
