class	test	description
LambdaTest	testCmpLegacy/testCmpLambda0	Comparators: lambdas and anonymous classes
	testCmpLambda1	(int x)->
	testOneArg	()->()
	testOneArg1 & 2	(x)-> aka x->
	testCmpLambda2 & 3	Integer bigger than 127
	testConsumer	Consumer in .forEach()
UroborosTest	*	chain call
CaptureTest	testLegacy	final fields in anonymous class
	testLambda	effective final with lambda
	testPredicate1 & 2	Predicates with context
ScopingTest	testScoping1	different this for anonymous classes and lambdas
FibonacciTest	test10	capture this but not field
	test10_static	without capture, just link to static method
MethodRefTest	testMethodRefStatic	methodRef to static method (as prev)
	testMethodRefInstance0 & 1 & 2	bound MethodRef
	testMethodRefInstanceUnbound	unbound MethodRef (add this)
	testConstructor	call new
	testConstructor0	constructor w/o parameters
	testConstructor1	constructor w/ parameters
ZamTest	*	Replace lambdas to MethodRef
ThreadLocalTest	threadLocalLegacy	legacy variant
	threadLocalLambda	added method withInitial(Supplier)
	threadLocalMRef	via MethodRef

###Default Methods

class	test	description
DefaultTest	*	backward compatibility
GuavaTest	testTreeMultiset	usage with third party libraries
StaticInterfaceTest	test	functional interface with static method

###Streams (Bulk Operations for Collections)

class	test	description
ExternalInternalTest	*
	►	highlight the difference between internal and external iteration
	►	iteration is explicitly serial
	►	libraries have more headroom optimizing with internal iteration
	►	sometimes even forEach is not enough: chaining the action within the serial again
