Add fillBuffer(_:) to RandomNumberGenerator

• Proposal: SE-NNNN
• Author: Alejandro Alonso
• Review Manager: TBD
• Status: Awaiting implementation

Introduction

This proposal aims to add a new method, fillBuffer(_:), to RandomNumberGenerator, and aims to move an already defaulted method into a requirement.

Synthesize default values in the memberwise initializer

• Proposal: SE-NNNN
• Author: Alejandro Alonso
• Review Manager: TBD
• Status: Awaiting review
• Implementation: apple/swift#19743

Introduction

State of the Memberwise Initializer

Prolog

Hello Evolution,

I want to discuss where we are with the current memberwise initializer for structures and where I wish to see this initializer evolve.

Refer to SE-0018 and SE-0018 Rationale. I do not speak for the author here, but I'm rathering pulling ideas and references from SE-0018 to formulate this post.

// Part one

let input = """

print(input.split(separator: "\n").map {
  Int($0)!
}.reduce(0, +))

// Part Two

// macOS x86_64 syscall works as follows:
// Syscall id is moved into rax
// 1st argument is moved into rdi
// 2nd argument is moved into rsi
// 3rd argument is moved into rdx
// ... plus some more
// Return value is stored in rax (where we put syscall value)

// Mac syscall enum that contains the value to correctly call it
enum Syscall: Int {
