Feature #5970: Add Enumerable#join with same semantics as Array#join

• Status: Assigned
• Assignee: matz (Yukihiro Matsumoto)
• Target version: -

[now (Nikolai Weibull)]

Currently, to join the elements of an Enumerable, you need to call #to_a on the Enumerable and then #join the result. With Enumerable#join one wouldn’t need need to create an intermediate Array.

Once Enumerable#join had been added, and was removed later. See Bug #1893 ([ruby-core:24786]).
