As I explained in Async property accessor: -> - #5 by mhofman, wavy dot is meant to enable avoiding intermediary await, allowing to pipeline the operations when they are performed on a remote system.
If operations execute in a single JS agent, then there is no difference with explicit awaiting, and the eventual-send effectively does that since the promise is decided locally.
The pipeline operator may help tidying the nested aspect without a new dedicated operator:
const posts = await fetch('/posts') |> await %.json();
