LizardScript 🦎

Основная информация

LizardScript - язык программирования:

• Скриптовый - LizardScript создан для взаимодействия с программами, написанными на C++. Он имеет наибольшее право называться скриптовым.
• Объектный - с помощью генератора метаданных METAGEN и скрипта make_metadata.py (спасибо Лёхе) из классов C++ извлекаются метаданные членов, и они становятся видимы в контексте LizardScript. Объявлять собственные классы в данный момент невозможно.
• Динамический - во время выполнения кода LizardScript можно компилировать новые функции с исходным кодом, заданным строковыми переменными.

Программист на LizardScript называется скриптолиз.

FAQ: Зачем ещё один скриптовый язык?

Async/Await for Swift

• Proposal: SE-XXXX
• Authors: Chris Lattner, Joe Groff

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.
