API Proposal: Pipe.Deconstruct

[AArnott]

A Deconstruct extension method should be offered for the System.IO.Pipelines.Pipe class so that someone can simply assign the reader and writer directly:

var (reader, writer) = new Pipe();

I like it.

@terrajobst, what are the guidelines for adding deconstruct methods?

[GSPP]

Is there a consensus on when to offer deconstruction in general? It can lead to confusing APIs and code. Like operator overloading it has really nice uses but it's easy to create unclear code where the only benefit is to save a few characters.

... and deconstructing with extension methods is trivial.

But for Pipe I believe it is a common enough case to "assign the reader and writer directly", so the deconstruct method would be nice.
