/**
* The `Live` trait provides access to the "live" environment from within the
* test environment for effects such as printing test results to the console or
* timing out tests where it is necessary to access the real environment.
*
* The easiest way to access the "live" environment is to use the `live` method
* with an effect that would otherwise access the test environment.
*
* The `withLive` method can be used to apply a transformation to an effect
* with the live environment while ensuring that the effect itself still runs
* with the test environment, for example to time out a test. Both of these
* methods are re-exported in the `environment` package for easy availability.
