An effect which allows a regular Monad m into the Sem ecosystem. Monadic actions in m can be lifted into Sem via embed.

For example, you can use this effect to lift IO actions directly into Sem:

embed (putStrLn "hello") :: Member (Embed IO) r => Sem r ()

That being said, you lose out on a significant amount of the benefits of Sem by using embed directly in application code; doing so will tie your application code directly to the underlying monad, and prevent you from interpreting it differently. For best results, only use Embed in your effect interpreters.

Consider using trace and traceToIO as a substitute for using putStrLn directly.
