You don't need to copy the array; creating an arrayref does that. And you can calculate the indices on the fly, so you need no temp variables or calls to splice. Just one expression: 
sub split_array_in_two {
    ([@_[0..$#_/2]], [@_[$#_/2+1..$#_]]);
}

for (0..5) {
  print map("<@$_>", split_array_in_two(1..$_)), "\n";
}
