Dear Masters,
How can I slice a hash given an array, such that after slicing it the original hash is shrinked (destructed). So, I mean how can I modify my code below 
perl -MData::Dumper -e '
%hash = (a => 3, b=> 4, c=>1 ,d=>7); 
@sel = qw(b c); 
@nhash{@sel} = @hash{@sel}; 
print Dumper \%hash;'

So that finally the original %hash becomes: 
$VAR1 = {
          'a' => 3,
          'd' => 7
        };

Is there a quick way to do it?
