Add option to generate a function

Hello, thank you for this macro. It is very useful because I really think that there is no need for a new syntax for something as simple as this.
However, there is a feature that I wish this macro has: being able to define new functions using the pipe macro. I use functional programming a lot, and one way to create point free functions is by piping several of them. If this macro provides that it will be perfect for almost any use case.

Regards
