It is other way around

I think he means the “special syntax” is the do ... end block because under the hood it’s a keyword list as @kylethebaker outlined. So do THIS end is the special syntax for [{:do, THIS}].

As @stevensonmt said - technically do CODE end is the special syntax, as you can easily remove it from language and it will only affect the readability, but will not impose any limitations. do-blocks are added on top of keyword lists, not other way around.
