[swift-evolution] ed/ing, InPlace, Set/SetAlgebra naming resolution

[Erica Sadun]

Assuming one would want to avoid the -ed suffix (and also -ing), one might consider:

* intersectionOf(), orOf(), unionOf() (or "With" over "Of")
* setIntersection(), setOr(), setUnion(),
* intersectionResult(), orResult(), unionResult(),
etc
