`while`, `until` and `unless` all implicate that the loop should break when the condition (or its negation) is met.
On the other hand, `where` as it is seems logical to me. Anyone who considers serious coding is likely to have basic knowledge of mathematics, so something such as ∀x ∈ X, x > 0 which translates into for x in X where x > 0 in Swift, which is pretty much how you'd read the mathematical statement. Yes, there is a comma, not `where` in the formula but when reading, you say "where" (unless you say "every x greater than zero"). > On Jun 13, 2016, at 5:26 PM, Erica Sadun <er...@ericasadun.com> wrote: > > >> On Jun 13, 2016, at 9:23 AM, let var go via swift-evolution >> <swift-evolution@swift.org> wrote: >> >> I am 100% with Charlie on this.
