[ruby-core:92433] [Ruby trunk Feature#15799] pipeline operator

[duerst@it.aoyama.ac.jp]

Issue #15799 has been updated by duerst (Martin Dürst).


Thanks for creating an issue.

The |> symbol looks reasonable to me, but I'd like to see more examples where this notation is preferable to 

```ruby
(1..).take(10).map {|x| x*2}
```

As for the assignment, just using parentheses looks confusing to me. It's clear we can't use `>=` or `|=`, but `|>=` or some other combination would be much clearer than just parentheses.

----------------------------------------
Implemented the pipeline operator `|>`, a topic of "ruby committers vs the world" in RubyKaigi 2019.
Also a casual idea of rightward assignment.

```ruby
1.. |> take 10 |> map {|x| x*2} |> (x)
p x #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
```
