Well, I wasn't going to hand it to you on a plate! ;-)

Personally I'd do it do it along these lines:

sub analyse_user_inputs
{
    my $r = shift;
    if (ref $r eq 'ARRAY') {
        return map { analyse_user_inputs($_) } grep ref, @$r
    }
    elsif (ref $r eq 'HASH') {
        return keys(%$r), map { analyse_user_inputs($_) } grep ref, va
+lues(%$r)
    }
    else {
        return
    }
}
