See issue #4869. I'm not quite sure what constitutes "consensus from the core team" (cf. discussion in the issue), but this at least demonstrates that the proposed change is pretty straightforward.
After this change, there are no new test failures. I've un-ignored the `to_str` vectors test; it's not at all obvious to me why it'd be problematic, and it passes on my Linux machine.
Major changes are:
- replace ~[ty_param] with Generics structure, which includes
both OptVec<TyParam> and OptVec<Lifetime>;
- the use of syntax::opt_vec to avoid allocation for empty lists;
cc #4846

* replace the dual next() and get() calls with a single next() function
* drop one of the pointer members from the struct
* add a method for using the lazy iterator with a for loop

#3406
Pretty straightforward. I'm using opaque pointers instead trying to get trans and core to agree on the types of the main function and crate map. One oddity is that this required changing the order of the `-lrustrt` argument to the linker in order to resolve `upcall_new_stack`. Linkers are mysterious.

After this patch, macros declared in a module, function, or block can only be used inside of that module, function or block, with the exception of modules declared with the #[macro_escape] attribute; these modules allow macros to escape, and can be used as a limited macro export mechanism.
This pull request also includes miscellaneous comments, lots of new test cases, a few renamings, and a few as-yet-unused data definitions for hygiene.
Address #2281

The first commit fixes warnings about `pub use` imports because it can't be known whether those are actually used or not.
The second commit fixes using `#[level(unused_imports)]` style control over the emission of warnings. Before it looked like it only worked as a command-line flag.
This pull request moves the logic from os::make_absolute() into the path module and fixes path joining for Windows. It does this by adding an ``unsafe_join()`` function that implements the operating system's path joining semantics.
Additionally it also adds an ``is_restricted()`` method to the trait which will return true if the path points to a windows device file.
Macro scope is now delimited by function, block, and module boundaries,
except for modules that are marked with #[macro_escape], which allows
macros to escape.
