I believe this patch incorporates all expected syntax changes from extern function reform (#3678). You can now write things like: extern "<abi>" fn foo(s: S) -> T { ... } extern "<abi>" mod { ... } extern "<abi>" fn(S) -> T The ABI for foreign functions is taken from this syntax (rather than from an annotation). We support the full ABI specification I described on the mailing list. The correct ABI is chosen based on the target architecture. Calls by pointer to C functions are not yet supported, and the Rust type of crust fns is still *u8.
