It would be good to include that information in the manual.  I only
see this in the man page:

              K      Produces a possibly-quoted version of the value of param‐
                     eter, except that it prints the values of indexed and as‐
                     sociative arrays as a sequence of quoted key-value  pairs
                     (see Arrays above).

The reader is left wondering whether it's eval-safe.

Also, I don't see the lower-case k transformation in the man page.
