[ruby-core:93188] [Ruby trunk Feature#15799] pipeline operator

Issue #15799 has been updated by shan (Shannon Skipper).


Seeing `|>` my assumption would be that you could use it in the functional style, so you could do:

``` ruby
42 |> Integer(exception: false) |> Math.sqrt
```
Instead of:

```ruby
Math.sqrt(Integer(42, exception: false))
```

Since this seems like the opposite direction of `|>`, might `<|` be an acceptable alternative to `>>>`?

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

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

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

----------------------------------------
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 {|e| e*2} |> (x)
p x #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
```
