[swift-evolution] SetAlgebra naming update

[Dave Abrahams]

Just an update:

The naming guidelines working group went back into negotiation over
the shape of SetAlgebra (and thus, Set and OptionSet) for
Swift 3, and reached a new consensus.  We intend to bring forward a
proposal for the API shown here:

  http://dabrahams.github.io/swift-naming/SetAlgebra-Math.html

and to update the guidelines to suggest using the "form" prefix to
create a verb phrase for a mutating method when the operation is
fundamentally non-mutating and described by a noun.

Regards,
