*	no null check for type-tested unapply arg	Adriaan Moors	2013-01-31	1	-0/+1
	pattern matching on case classes where pattern is not known to be a subclass of the unapply's argument type used to result in code like: ``` if (x1.isInstanceOf[Foo]) { val x2 = x1.asInstanceOf[Foo] if (x2 != null) { // redundant ... } } ``` this wastes byte code on the redundant null check with this patch, when previous type tests imply the variable cannot be null, there's no null check
