[swift-evolution] Brace syntax

There is not in fact an emphasis on conciseness. This has been repeated many times by the swift team. Conciseness is not a goal of Swift, but expressiveness absolutely is. Braces are a well-understood and simple way to express the notion of a scope/closure. And FWIW removing braces means you have to come up with a completely different syntax for closures, because indentation does not suffice there.

Also, "don't be like C" is not even remotely a goal of Swift. The Swift syntax is C-like in many respects. "Be like C" isn't a goal either of course, but when deciding between two alternatives that have no compelling arguments either way, picking the one that would be more familiar to Obj-C programmers is usually a good idea.

There already seems to be a general emphasis on conciseness,  lack of redundancy, and a modern syntax. e.g. semicolons are not required for single-line statements; brackets have been removed from if/for/while expressions, compared to C-style syntax. So, why not go the whole way in breaking the C-style connection? The present syntax seems to be shunning C, but only slightly.
