Elixir's optional syntax

I always knew that Elixir had some optional syntax, but I didn't realize how prevalent it was!
José Valim shared a new guide on Elixir's optional syntax. And I thought it was really cool! So, I made this video to share an example.

It is pretty cool.

Just started my elixir journey (my day job is kernel stuff) as I found so many similarities between the BEAM VM and some of the scheduling "internals" in Linux Kernels. I'm a decent way through Dave Thomas' Programming Elixir Book (a very good read). Anyway, 01:35 blew my mind. Your short video just did a massive stack unwind on a lot of the "fundamentals" of basic program structure. Man am I glad the KZbin algorithm brought me here.

Wow, so much more readable at the end. Thanks

Don't know if I love it or hate it lol. If you go overboard, it can look like a ton of nested ternary statements. But for simple functions, this is pretty cool.

😅 I don't think it's "optional" in the sense that we should write Elixir code like that. It's just interesting to know that it's syntactic sugar. And it's helpful if you do any metaprogramming.

Lisps all the way down
