…mpletion Previously the operation states for let_value, let_error, and let_stopped directly contained the operation states of one or two child operations. When first connected this number was one, and after the completion of that first operation and the connection of the sender returned by the wrapped invocable the number was two. Notably when the second operation state is connected the first operation has completed. P3373 proposes changing the above behavior such that after the tuple of values sent by the first operation is populated the operation state for the first operation is destroyed. Thereafter that storage can be reused for the operation state of the second operation thereby: - Release resources held by the first operation state sooner, and - Reducing the size of the operation states of let_value, let_error, and let_stopped This commit implements the above-described change.
