Thank you all very much. I have tried to search "perl discussion" and it brings me to perl6's list page. Yes for data analysis we primarily use classic perl5, which is smart enough especially the regex matching. There are "spark streaming", "flink streaming", "storm streaming", and a lot of others, but they don't support perl language well. So I expect the community, either perl6 or perl5, can make that a framework. We can't lose the capability in big data, cloud computing, AI, ML, streaming, these are the main features of current internet. Everyone today writes CGI with perl? NO.
Thanks.
