We have a lot of conversion methods such as `#to_str`, `#to_json`, ... But there is no implicit transition from having e.g. `String` object to `URI`. I'd rather see something like `client_api_url.to(URI)` which could be equivalent of `URI(client_api_url)`.

I have seen previous discussions around introducing a pipe operator, but it seems the community didn't reach a consensus. I would like to revisit this idea with a simpler approach, more of a syntactic sugar that aligns with how other languages implement the pipe operator, but without making significant changes to Ruby's syntax. Currently, we often write code like this: ```ruby value = half(square(add(value, 3))) ``` We can achieve the same result using the `then` method: ```ruby value = value.then { add(_1, 3) }.then { square(_1) }.then { half(_1) } ``` While `then` helps with readability, we can simplify it further using the proposed pipe operator: ```ruby value = add(value, 3) |> square(_1) |> half(_1) ``` Moreover, with the upcoming `it` feature in Ruby 3.4 (#18980), the code could look even cleaner: ```ruby value = add(value, 3) |> square(it) |> half(it) ``` This proposal uses the anonymous block argument `(_1)`, and with `it`, it simplifies the code without introducing complex syntax changes. It would allow us to achieve the same results as in other languages that support pipe operators, but in a way that feels natural to Ruby, using existing constructs like `then` underneath. I believe this operator would enhance code readability and maintainability, especially in cases where multiple operations are chained together.
