Re: Clubbing array elements together:

What's wrong with a foreach approach?

$ perl -Mstrict -MData::Dumper -e '
my @words=("",",","abcd","efgh","","","jklm","nopq","");
my $combined;
my @combinations;
for my $word (@words){
  if ($word){
    $combined .=$word;
  }
  else{
    push @combinations, $combined if $combined;
    $combined="";
  }
}
@words=@combinations;
print Dumper\@words;'
$VAR1 = [
          ',abcdefgh',
          'jklmnopq'
        ];
