[swift-evolution] Standard library 'Data' type pre-proposal

[Austin Zheng]

I think hex encoded string conversion is a important use case. Another idea - instead of making the Data type itself generic, there can be a generic Data.View<T : IntegerType> into the data, or the Data type can come with a number of Views for each of the fixed-width integer types.
