>About the only wart I've seen so far in Elixir is the pin operator[6], but that was necessary to preserve the name-rebinding ability in a pattern-matching context, and it stops seeming like a wart fairly quickly, once you realize why it's necessary.

I'm interested in hearing more on this, because I find elixir's pattern matching phenomenal. Fully embracing it feels like such a paradigm shift, and along with the rest of elixir it feels like I'm learning programming all over again (and I've been doing this for over a decade). I love it.

Back to the pin operator - the syntax is very light, and it's conceptually simple. As you said it's a natural consequence of pattern-matching. I'm not trying to start bikeshedding here, just wondering if there are some other problems or perspectives with the pin operator I'm not aware of. Thanks.

I haven't really seen any. You can't use the pin operator in argument lists to functions... that's the other "gotcha".
