List-ops: make code blocks more perlish?

Programming Perl 5

I was experimenting with making the functions more perlish: wouldn’t it be nice to do

filter {$_ > 5} $list

# or
$sum = foldl {$a + $b} 0, $list

I (re)discovered that $a and $b are special globals, so we can do stuff like

$ perl -MData::Dump -Mexperimental=signatures -E '
        sub myreduce :prototype(&@) ($code, $initial, @items) {
          $a = $initial;
          for $b (@items) {
            $a = $code->();
          }
          return $a;
        }

        dd myreduce {$a + $b} 1, 2, 3, 4, 5;
        '

Should we do this for list-ops?
