Footnote from page 3:

> Elixir can be regarded as a modern Erlang (e.g., with macros) that runs atop BEAM; i.e.,the Erlang virtual machine.

I've heard quite a few descriptions of Elixir, relative to Erlang, but I'm not quite sure about this one. Erlang has macros[0], though the syntax and general format does differ from that of Elixir's[1]. And though Erlang has been around since at least 1986, it has changed a lot in that time and is what I'd consider to be a modern programming language today, used at places such as WhatsApp, Grindr, Pintrest etc...
