Very close. Try this instead:
foreack $k (keys %$hash) {
print "$k => $hash->{$k}\n";
print "$k => $$hash{$k}\n"; # equivalent
}
The code you have above is for a hash named
%hash, not a reference to a hash contained in a scalar
$hash. Notice that in the code above, the sigil preceding the variable is always a
$.
For more info on references in general, take a look at perlref and perlreftut.
