A TC39 proposal for ECMAScript introducing a `::` operator for `this` binding and method extraction, enabling syntactic sugar like `obj::method` and 'virtual method' library pipelines. The repository contains the specification text, examples, and links to prototype implementations in Babel and esdown.

Use cases

• extract a bound method from an object in JavaScript
• call a function with a specific this value without .call()
• chain virtual methods from libraries like jQuery or iterator helpers
• understand the history of the ECMAScript bind operator proposal
• evaluate stalled TC39 syntax proposals for language design research

When to choose

• you are researching TC39 proposal history or language design
• you want to experiment with the :: operator via Babel's prototype support
• you need reference examples of method extraction syntax

When to avoid

• you need a syntax that works in production JavaScript engines - the proposal is stalled and unsupported
• you want a runnable library or tool rather than a specification document
• you need modern alternatives like arrow functions or Function.prototype.bind
