The array-backed and quarternary parts of this are implementation detail. Do they need to be in here? Are we guaranteeing that will be the case forever more?

I'm thinking that this is more informational rather than a behaviour users would rely on. As such, we could always update the docs as we evolve the implementation without consequence.

Is this three space indent the intended formatting? We generally don't use that elsewhere to my knowledge.

Not sure what the standard formatting is TBH. I expect that @carlossanlop's tool will eventually force a uniform style as we backport content from dotnet-api-docs.

I'm assuming most users would want to know what differentiates this method over just calling Enqueue();Dequeue()
