Description
Alternative title from Meyers15: Avoid default capture modes
As practical experience beyond Scott's extensive analysis from his Item 31, we've seen benefits from requiring developers to explicitly list all of the variables used within the lambda. Specifically it forces examination of the lifetime of each object in cases where the lambda may be executed asynchronously.
