Thanks for the link! I hadn't seen that one before. While I think I'm already thinking in expressions, Erlang's placement of punctuation never really made a lot of sense to me. Maybe that explanation will finally clear up my confusion.

So far, I agree with the note about 0/1-based indexing. It's just not used a lot. However, I find it pretty calming that indexes will work the way I expect them to, should I ever need to use them.

Now that I think about it, these two points (syntax and indexes) are somewhat petty things to point out about the Erlang : Elixir relationship, and I feel a bit bad for repeating them in the blog post. Things like protocols are way more interesting (and hopefully, are what drives you to try out Elixir). (-:
