	// Package multiwrap implements support for wrapping multiple errors into a
	// single error value that supports the Go 1.13 Unwrap(), Is() and As()
	// interface. It's similar to go-multierror [1].
	//
	// This is a proof of concept and I'm looking for feedback! Maybe somebody has
	// already done a nicer version of this idea?
