I recently started using rust-analyzer with vscode.

One common sight is this:

thing

  .stuff()  

  .other()  

  .whatevs()

Each of the calls returns a different type. Rust-analyzer displays the return type of each call to the right of it.

I imagine something similar could reconcile the benefits of terseness with readability and discoverabilty.

The blog post already has the prototype:

+ / ! 100

plus reduce range 100

Imagine the second line being added in by your ide in a light gray.
