Damn, I should have remembered that. Especially considering I had a project where I had to trawl through the ruby parser including multiple assignment rules.

To be fair, I find the destructuring syntax strange in Ruby. For example, why do I need the splat on the list? It doesn't make sense to me. I'm sure there is a good reason buried in the implementation, but if I were to design the syntax, I don't think I would do it that way.

You don't on the RHS, or rather, it's redundant in the given example. On the LHS you need it to prevent single element capture.. and within the ruby language, it's a fairly consistent sigil.

Wow. You're right. I'm not sure how I got that wrong. I'm sure I tried it. Thanks for correcting me!
