Oops. Thinko. Mine should obviously be -= and - (instead of += and +). I hate the limited edit time on EE.
When you say "without writing an explicit foreach loop", I'm not sure if you'd prefer an implicit foreach loop, or an explicit map loop, or to invoke code that someone else has already written, but you could also
use Operator::Util qw(hyper);
hyper('-=', \@arr, 2, dwim_right=>1) ;
use Operator::Util qw(hyper);
hyper('-=', \@arr, 2, dwim_right=>1) ;
