It worked. Thanks!!! Actually when I was initially installing one of the WebSocket modules, the module Future::IO was marked as a dependency which was not being resolved by CPAN installation process. I manually installed Future::IO. Upon your advice I uninstalled Future::IO via cpanm and then installed IO::Async::Loop which worked.
So it comes down to four things: First, Socket was to be upgraded. Second, Future::IO was unnecessary installation. Third, no bug in tests. Fourth, no problem with Perl distribution and windows 10 platform. :)
