I really, really hate all of those arguments stating "that we should care only about the present, not the future" and that even though `#[...]`/`@[...]` might bring benefits in the future, we should still choose `@@`". This shows clearly that some people are basing their views on subjective reasons rather than being objective. As far as this discussion is going, I see pro-`@@` people just saying "Arghhh, let's keep @@, it doesn't bring any benefits that other syntaxes do but we don't need them anyways, let's not speculate future". It's like saying you can either go through door A and get a free car or through door B and get the same car and **maybe**, even an additional 1,000$. We are playing probabilities here but at the moment, no one has said any substantial argument why `@@` is better and thus, `@[...]` seems like a better option in the long term. > > - Doesn't allow grouping > > I do not understand this argument, what is the point of grouping for @@? > Does grouping mean anything special for other syntaxes, or is it just to > save > keystrokes?

You are basing your opinion on subjective views which goes against this RFC's principles - to choose a syntax that is the best based on the benefits it offers. > - No forwards compat with PHP 7 > > But no BC break either, while #[] introduces BC break. > Not true, technically speaking both `@@` and `#[]` have a BC break. Albeit `@@` has a smaller one. But by sacrificing a few very old codebases (that still use `#` not `//`), we are making sure that we won't run into any parsing problems in the future.

Heck, `@[...]` is the closest to both `@` and `[...]`. Best regards, Benas >
