…knowing how to write them is a good thing. I typically use macros to write more expressive guard clauses, but you can do whatever you want with them. Chris McCord wrote an excellent book on macros, called Metaprogramming Elixir, if you want to know more about them.
你现在去搞元编程还为时过早。它的规则确实很简单，但深入玩宏之前，建议还是先对这门语言足够熟练。你或许可以去读读 Chris McCord 的《Metaprogramming Elixir》，作者本人也是 Phoenix 的创作者之一。
It’s too early for you to try metaprogramming. It has very simple rules but proficiency with the language is advised when diving into macros. You might want to read Chris McCord’s “Metaprogramming Elixir”. The author is also one of Phoenix’s authors.

……懂得怎么写它们是件好事。我通常用宏来写表现力更强的 guard clauses，但你想拿它干啥都行。如果想深入了解，Chris McCord 写过一本很棒的讲宏的书，叫《Metaprogramming Elixir》。
