I think we had decide to only allow tail calls inside a crate. In part because of limitations on which calls llvm guarantees are tail. But I would vote for dropping tail calls. Even if we do them inside crates only, there is still a mismatch with rust where "tail" is a property of the call only and llvm where the callee must know it is can be tailcalled.
