Given the following hash: 
my %hash = ('one' => 1,
        'two' => {'one' => 1,
              'two' => {'one' => 1,
                    'two' => 2,
                    'three' => 3}},
        'three' => 1);

I need to know if a given key equals a value or is a hash ref. The following code performs the check that I need, but only if strict is turned off: 
if ((keys %{$hash{'one'}})) {
    print "Yes\n";
}
else {
    print "No\n";
}

When Strict is being used it yields the following error, "Can't use string ("1") as a HASH ref while "strict refs" in use." What would be the best way to do this and leave strict enabled?
