Well, Java has since introduced RuntimeIOException, which could be used in cases where an IO exception is unexpected, so we could introduce a new class, say, ErrorCheckingPrintStream, and add the method `ErrorCheckingPrintStream withErrorChecks()` to PrintStream if it's considered sufficiently worthwhile. So you could have:
System.out.withErrorChecks().println("Hello World!);
But we can't change the behaviour of the existing PrintStream.
