Monks,

I'm trying to check that a number of elements exist in a Hashref. Instead of checking for one element at a time, I'd like to do the check them all in one pass.

The following code is what I've tried so far, but I'm getting some unexpected behavior. It looks that it only check s for the last element in the slice

sub add_ingredient {
  my $args = shift;

  if ( @{$args}{ qw/name unit quantity/ } ) {
    print "All elements exist\n"
  } else {
    print "Hey some information is missing \n";
  }
}

add_ingredient({                  
  name => "carrot",
  unit => "lb",
}); #output: Hey some information is missing


add_ingredient({                  
  quantity => 1.0,
}); #output:  All elements exist

Is this the correct way to check for element existence?

Please enlighten me ...Thanks
