Re: [RFC] Square bracket syntax for array destructuringassignment

Hi Ivan, Ivan Enderlin wrote:

Thanks a lot for this RFC. Huge +1 from the all Hoa's community and myself. However, did you discuss about […] vs. {…}? Most of the time, arrays or vectors constructing are represented by […] symbols while destructing are represented by {…}. What your point of view or arguments here?

I'm not sure I understand what you mean. In JS, for example, you use {} to create an object or for destructuring assignment for an object. But you don't use {} for other cases. [] is used to create arrays and for destructuring assignment from arrays. The pattern resembles the syntax for constructing what it matches against. In Haskell, (…,…) is used for constructing a tuple and pattern-matching against it. I can't think of a language where {…} is used for destructuring or pattern-matching against something which is not written with {…}. Does that make sense? -- Andrea Faulds https://ajf.me/
