Coming from Erlang, I think macros are one of the things I'm ambivalent about in Elixir. There are a bunch of actual improvements besides just the syntax itself in Elixir, like string handling, but things like macros in Ecto ... not yet a fan of that.
Some interesting insights from the article:
"Elixir itself is heavily powered by macros. Many constructs, such as defmodule, def, if, unless, and even defmacro[1] are actually macros...."
