And did you think about the edgecase of choosing a wrong delimiter which already appears in the elements? ;)

FWIW, I'm quite often in a situation where I would prefere to apply regexes on lists, so I started meditating yesterday about a module abstracting the delimiter problem away by locally redefining a special var like $; or $\ for the delimiter and $_ for flattened list.

something like

@newlist = flat { s/START$;(.*)$;END/$1/ } @list
 
sub flat (&@) {
  my ($code,@list) = @_;
 
  local ( $;, $_ ) = join_reliably (@list);
 
  $code->();
 
  return split $;, $_
}

untested.

Cheers Rolf
