in reply to s/// with 2 arrays

Does the order of the substitution matter? If not, try:
my %subst; @subst{@first_half} = @second_half; s/\Q$_\E/$subst{$_}/ for keys %subst;
Or if order does matter:
for (my $i = 0; $i < @first_half; $i++) { s/\Q$first_half[$i]\E/$second_half[$i]/; }
You may want to remove the \Q\E from each s/// if the REs aren't just strings, but have meta-chars in them, and you'll have to bind the s/// to whatever variable has the line in it too, of course.
