不可变类和构建器，使得错误操作更难实现。

CacheableBool

# Never forget cacheability.
CacheableBool::create($bool, $cacheability)
CacheableBool::createTrue()
CacheableBool::createFalse()
$cacheableBool->value()
assert($cacheableBool instanceof CacheableDependencyInterface)
CacheableBool::fromAccessResult($accessResult, $useNotForbidden = FALSE)
$cacheableBool->toAccessResult($useNotForbidden = FALSE)
CacheableBool::not()
CacheableBool::and(...$cacheableBoolItems)
CacheableBool::or(...$cacheableBoolItems)
