gab\fiber

Fibers are created with Fibers.make:, which takes a block and immediately queues it for execution. The fiber may run on any OS thread managed by gab’s runtime.

Fibers.make () :: do
  'Hello from a fiber!'.println
end

This returns a fiber value. When printed, you’ll see something like:

<gab\fiber 0x7fed60004770 : <gab\block gab\main:1 1>>

This describes:

• The message sent, : (The empty message)
• The receiver, a gab\block

You can spawn fibers which send any message to any value, and you can also add arguments!

Fibers.make (1 +: 1) .await
