Overview

This “circuit” is optimized for

a) merging speed at run-time, since features like tracing will be applied here.
b) execution speed. Every task in the real circuit is wrapped with one of us.

It doesn’t come with built-in insertion mechanics (except for Pipeline.prepend). Please add/remove steps using the Adds methods.
