*	SI-8001 spurious "pure expression does nothing" warning	Eugene Burmako	2013-11-23	1	-0/+1
	`isPureExprForWarningPurposes` doesn’t warn on `()`, but `(): Unit` leaves it confused. This patch fixes the problem. The fix is important in the context of the recent split between blackbox and whitebox macros. Macro engines wrap expansions of blackbox macros in type ascriptions, so a macro that expands into `()` would actually produce `(): Unit`, which would trigger a spurious warning. Thanks @milessabin for spotting this problem!
