[erlang-questions] Any Erlang Devs Contemplating Elixir?

I think if you seriously want to push macros then LFE, or any other lisp
for that matter, is a much better option. It is much more straight-forward
and readable. It also gives you the option of creating new syntax which
Elixir macros don't. Elixir has a slightly "lax" syntax which allows you to
hide that everything is a function call but you can't create new syntax.

Of course some people lisp doesn't actually have any syntax but I prefer to
view it as being very simple and very consistent. :-)
