Say I have an array of hashes like this:

@response = [ { 'name' => 'foo', 'id' => 'bar', 'self' => 'baz' }, { 'name' => 'foo2', 'id' => 'bar2', 'self' => 'baz2' }, ]

Now I have a subroutine called filter which I call like this:

my $responseref = \@response; my $filtered_response = filter ($responseref, 'name', 'id');

How would the subroutine need to look to get an array reference as return value of which the array would look like:

@response = [ { 'name' => 'foo', 'id' => 'bar', }, { 'name' => 'foo2', 'id' => 'bar2', }, ]

Ideally it should work without installing any additional modules
It should also be pretty generic, it should for example be able take a different amount of fields to filter through every time
