I've been looking at the possibility of re-habilitating the half-proposal of three years ago to only propose single quoted string literals as an alternative syntax for Character and Unicode.Scalar literals. It's difficult writing the motivation section without mentioning the eventual plan to implement the integer conversions. In which case, why would one review one without the other?
This comes about as there is a subtle difference between this proposal and that last reviewed in that rather than being about distinguishing between String and Character literals it is actually closer to the very original pitch in that it is more oriented towards the conversions of these literals to integer constants. One could of course create an implementation of '1' being a synonym for the integer constant 49 but the proposal seeks to offer more flexibility using Swift's type inference and the ExpressibleBy protocols to offer also a Character identity (as is the element of a String) which some find overly complicated.
I don't know where to go from here. If the review manager would offer to bring to review a revised two step proposal making the case as best I can, I would prepare for that. What I can't do is randomly prepare proposals that never come to review.
