Allows for convenient use in do-notation.Note that the application of ! is not an action in the 6 context, as $ is in the I type. While the fresh bindings in the following example will force the !+ expressions to be reduced every time the do-block is executed, traceM "not crashed"_ would only be reduced once, and the message would only be printed once.
