(I'm not sure if I really understood your problem...)

what about creating a new array instead of slicing? 

for (@old) {
  push @new,@pre if /START_RE/;
  push @new,$_;
  push @new,@post if /END_RE/;
}

UPDATE:

Generally it's better to use an iterator that returns separated records.

Have a look at the "alternativ iterator" Re^2: reading several lines in a gulp (iterator) and change the last condition to split at /^=====================/
