I want to define an anonymous hash by taking a slice of a pre-defined hash. How might I do so? 
%parm = (
     1 => 2,
     2 => 3,
     3 => 4,
     4 => 5,
     5 => 6 );
    

# useful for $object = Class::Name->new($x); 
# where only a subset of %parm is needed

$x = { @parm{2..4} };   # fails
$x =  \@parm{2..4};     # fails
$x = { 2 => $parm{2},   # trying to avoid
       3 => $parm{3},
       4 => $parm{4} }; 

use Data::Dumper;

print Data::Dumper->Dump([$x],['x']);
print $/;
