[swift-evolution] [Pitch] Moving where Clauses Out Of Parameter Lists

[Sean Heber]

This almost seems like it could work so that it didn't even need the bracketed parts to be able to figure out the types:

func anyCommonElements(lhs: T, _ rhs: U) -> Bool where
    T : SequenceType,
    U : SequenceType,
    T.Generator.Element: Equatable,
    T.Generator.Element == U.Generator.Element
{}

.. which would address my concerns about distance from names to params, too!
