Go2

Go2 status

This page tracks the status of "Go 2".

Go 2 is in a very early, planning phase.

Bugs

• Open Go2 bugs

Talks

• GopherCon 2017: Russ Cox - The Future of Go
• GopherCon Russia 2018: Brad Fitzpatrick - Go: Looking back and looking forward (Go2 stuff is at about 20 minutes in)

Scope

From talk above:

• "maybe three major changes"
• plus minor housekeep tasks
• TBD

Examples of major changes:

• versioning
• generics?
• simplified, improved error handling?
• ...

Examples of housekeeping:

• Open Go2Cleanup bugs (please don't add this label to things without discussion)

Compatibility

We do not want to break the ecosystem. Go 1 and Go 2 code must be able to interoperate in programs with ease.

Standard library

The standard library would probably be versioned and permit out-of-cycle updates, but be included with Go releases. Maybe "encoding/foo" become shorthand for "golang.org/x/std/encoding/foo". TBD. Some package would probably get v2 major versions, but the v1 versions would be minimally maintained, at least for security.

Roadmap

TBD
