Big 👍 here. |

+1, and we should make the plan known to as many in the community as possible, so people will not assume that Rust is never going to have a proper tracing GC. |

Sounds good! |

Take 'em out - keep things clean as possible. Chances are the future GC will end up having different lang items, and in any case it is no bother to add more lang items.

@pnkfelix: Would it be possible to just include output from a run of the sample program, so that we don't need to run it in the playpen (or compile it locally) to see what it's demonstrating? |
Revise the printouts as well to be clearer about each cases' intent.

Accepted as RFC 67. Discussion. Tracking. |
Summary
Remove the reference-counting based

tracing GC, and will avoid people getting incorrect impressions of
Rust based on the current reference-counting implementation.
