This document specifies the pipeline operator |>
. See the explainer for an introduction.
The main design decisions made in this specification are:
|>
is treated directly as a function; even if it is a x |> y(z)
is similar in semantics to y(z)(x)
. bug|>
sits between the ternary operator and ||
. It is left-associative. bugeval
are indirect eval.|>
is evaluated before the right one.|>
has a receiver, it is used for the call, with rules similar to a method call. That is x |> y.z
gets y
as a receiver, just as if it were written y.z(x)
