\and it functions fine.  Change true && to false && and it prints false
\correctly as well.

The abovementioned method has different characteristics:

	test-command && {
		if-clause
	} || {

	}

...will execute the else-clause if the test-command *or* the if-clause fails,
which might not be what you want.
