 That's when `unquote_splicing` becomes handy:

 Unquoting is very useful when working with macros. When writing macros, developers are able to receive code chunks and inject them inside other code chunks, being able to transform code or write code that generates code during compilation.

-Note that in our macro implementation, the sentence was not printed, although it was printed in our function implementation. That's because the arguments to a function call are evaluated before calling the function. However macros do not evaluate the arguments, instead they receive the arguments as quoted expressions which are then transformed into other quoted expressions. In this case, we have rewriten our `unless` macro to become an `if` behind the scenes.
