Description

That would make it easier to work with stdout, stderr, and other file handles. For example, using stderr with Swift.print().

Currently, every project has to include this extension:

extension FileHandle: TextOutputStream {
	public func write(_ string: String) {
		write(string.data(using: .utf8)!)
	}
}

Swift 4.2
