Disclaimer: I have not (yet) prepared a proposal, or even something that could be considered a draft, but I want to hear public opinion on the topic.
SE-0077 (about precedence groups) has been successfully implemented for Swift 3. (A thousand thanks to John McCall!) It suggests a model where we can prohibit certain operators from standing next to each other. This was intended to be the second part of that proposal. We now have to think if we should drop some precedence relationships between standard operators. Here are examples of parentheses dropping that can be ambiguous to reader: 1/3 as Double // should we prohibit this? 1 | 2 ^ 3 // or this? a && b | c // or this? Should we break standard precedence hierarchy and if yes, how? For those involved in the mentioned proposal, how exactly should standard precedence groups relate?
