[swift-evolution] [Pitch] New Version of Array Proposal

[Taylor Swift]

Between comma, semicolon, and colon, I think semicolon is the best choice
(though I would prefer double colon over all three). However I don’t think
we should discard possible alternatives just because they aren’t already
reserved separators. Neither ',', ';', ':', nor '::' is particularly
readable, and compiler parser code only needs to be written once, while
language syntax, once it’s decided on, is stuck with us forever.
