# GC Extension

## Introduction

Note: Basic support for simple [reference types](https://github.com/WebAssembly/reference-types/blob/master/proposals/reference-types/Overview.md), for [typed function references proposal](https://github.com/WebAssembly/function-references/blob/master/proposals/function-references/Overview.md), and for [type imports](https://github.com/WebAssembly/proposal-type-imports/blob/master/proposals/type-imports/Overview.md) have been carved out into separate proposals which should become the future basis for this proposal.

See [MVP](MVP.md) for a concrete v1 proposal and [Post-MVP](Post-MVP.md) for possible future features.

WARNING: Some contents of this document may have gotten out of sync with the [MVP](MVP.md) design, which is more up-to-date.


### Motivation

* Efficient support for high-level languages
  - faster execution
  - smaller modules
  - the vast majority of modern languages need it

* Provide access to industrial-strength GCs
  - at least on the web, VMs already have high performance GCs
