[swift-evolution] SE-0183 - Substring performance affordances

[Chris Lattner]

Hello Swift community,

Context: One more small refinement proposal for Swift 4 strings.  We are specifically not opening the floodgates for new proposals yet, this is this simply one potential small-scope refinement to an existing Swift 4 feature.


The review of "Substring performance affordances" begins now and runs through July 21, 2017. The proposal is available here:
https://github.com/apple/swift-evolution/blob/master/proposals/0183-substring-affordances.md

Reviews are an important part of the Swift evolution process. All reviews should be sent to the swift-evolution mailing list at
https://lists.swift.org/mailman/listinfo/swift-evolution

or, if you would like to keep your feedback private, directly to the review manager. When replying, please try to keep the proposal link at the top of the message:

What goes into a review?

The goal of the review process is to improve the proposal under review through constructive criticism and, eventually, determine the direction of Swift. When writing your review, here are some questions you might want to answer in your review:

	• What is your evaluation of the proposal?
	• Is the problem being addressed significant enough to warrant a change to Swift?
	• Does this proposal fit well with the feel and direction of Swift?
	• If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
	• How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
