Now base::lambda can be copied and can wrap any immutable lambda. For mutable lambdas there is base::lambda_once (which you're supposed to call only once to pass data through lambda captures, for example by using std::unique_ptr). Generally base::lambda is passed by value and base::lambda_once is passed by rvalue reference.
