in thread A question about method return values and error checking

I've been thinking about it and I am leaning toward this. We had no idea that it might even return undef. What operating system has no name? And with the docs like they were, it's just not something we accounted for. But the logical defined or looks like the way to go.

    If you wanted to be particularly crazy, you could even go with: 
    printf "Operating System: %s\n", $os->name( long => 1 ) 
                              // (`uname -o -r` =~ s/\n//r)
                              || 'undefined';
