I'm curious - why not something like this?

# note the trailing comma at the very end of the list
my @option_config = ( $UNIQUE_OPT,
                      $FORCE_OPT,
                      $VERBOSE_OPT,
                      $OUTPUT_EXT_OPT,
                     );

As far as making it into the language, I would vote no. I fail to see the benefit. Why quote, interpolate then split into a list when it's no more effort to create a list in the first place?
