Subject: [ruby-core:67844] [ruby-trunk - Feature #10726] [PATCH 4/4] * New	methods: Set#power

Issue #10726 has been updated by gogo tanaka.


@ Shota Fukumori, @Marc-Andre Lafortune
> * Write description of your proposal in the ticket.

Implement method which returns set of all subsets of +self+.

> * What is your use case?
> I don't see myself ever using this and also wonder who would and in what circumstances.

As for me it was necessary for solving some combinational problem or optimization.
I believe power set is essential with collection of unordered values with no duplicates. 

But if you guys think It isn't worth it, I'm ok in that case.

> I think there's no need to split patches for same purpose... at this case patch except the last one should be one patch file.
> powerset or power_set would be a more appropriate name.


OK I'm gonna resend patch in doing so.
