This is an experimental RFC for adding a new feature to the language, coroutines (also commonly referred to as generators). This RFC is intended to be relatively lightweight and bikeshed free as it will be followed by a separate RFC in the future for stabilization of this language feature. The intention here is to make sure everyone's on board with the general idea of coroutines/generators being added to the Rust compiler and available for use on the nightly channel.
Relevant to the language team, which will review and decide on the RFC.

Generator support
This adds experimental support for generators intended to land once rust-lang/rfcs#2033 is approved.
This is not yet ready to be merged. Things to do:
- Make closure arguments on generators an error
- Spot FIXMEs
- Pass make tidy
- Write tests
- Document the current syntax and semantics for generators somewhere
- Use proper error message numbers
-
Make the implicit argument type default to()
