This is orthogonal to the discussion that happened in your thread, definitely no discussion of any changes to the requirements. :)
We are discussing this proposal: https://github.com/apple/swift-evolution/blob/master/proposals/0041-conversion-protocol-conventions.md <https://github.com/apple/swift-evolution/blob/master/proposals/0041-conversion-protocol-conventions.md> and specifically the use of the `Convertible` suffix for both the `*LiteralConvertible` protocols and the `Custom(Debug)StringConvertible` protocols where the conversion runs in opposite directions.
The core team decision was:
"The feedback on the proposal was generally positive about the idea of renaming these protocols, but the specific names in the proposal are not well received, and there is no apparent confluence in the community on better names. The core team prefers discussion to continue -- if/when there is a strong proposal for a better naming approach, we can reconsider renaming these."
>> At the same time, it continues to bother me that `Convertible` is used by standard library protocols with two completely different meanings. This is a problem that deserves to be solved and as it involves a breaking change Swift 3 is the right timeframe in which to do so.
>> If the core team is able to indicate an approach they favor I would be willing to revise and resubmit the proposal. But I don’t want to spend any further time speculating about what solution might be considered acceptable.
