A few test runs for fun.
Proposal SE-0071. “Allow (most) keywords in member references” is implemented. This allows the use of members after a dot without backticks, e.g. “foo.default”.
Not quite ready for prime time. Chris Lattner tweets: “Fwiw, that is the intended design of SE-0071. It only changes “after the dot”. You need to use back ticks after [v]ar”
Proposal SE-0046. Function parameters now have consistent labelling across all function parameters.
Proposal SE-0037. “Comments are now treated as whitespace when determining whether an operator is prefix, postfix, or binary. Comments can no longer appear between a unary operator and its argument.”
Proposal SE-0031: inout now decorates types, not labels
