The GoTwo Programming Language.
GoTwo is a friendly parody fork of the Go programming language, focused on implementing all sorts of wild and whacky features that do not belong into Go. Unlike Go, it comes with a guarantee of instability: every release is gauarnteed to break existing code, and GoTwo may not be compatible with mainline Go at all in the future, although the essential features of the Go language will be kept.
It goes without saying that GoTwo is not intended for serious use, rather this project is supposed to be a playground for ideas that the Go language cannot or should not implement.
Contributions
Make a pull request with the feature you'd like to implement, preferably including tests and some specification. If it actually works, and doesn't break too many other things, I'll probably merge the request. Probably.
