> Use the return keyword in a lambda, it returns from the lambda, just like if you call return in a method. In a block or Proc, it returns from the calling method. In a block or proc, it returns from the method in which the block/proc was defined, not the calling method. These may or may not be the same; the proc may be called deeper in the call chain, or it might (erroneously) be called after the defining method had exited, producing a LocalJumpError. This also means that implicit returns from a block/proc have different semantics than explicit returns, unlike lambdas/methods where implicit returns have the same semantics as explicit returns. (From a block/proc, the last evaluated expressions behaves as if it were passed to "next" rather than "return", resulting in a local return to the calling method rather than a return from the defining method.)
