While reading the intro, I was confused as to why there were two variables named "numbers". Unless I'm mistaken and it's not necessary, let's get rid of it to make it clearer.
This breaks code like:
struct Foo {
...
}
pub fn make_foo() -> Foo {
...
}
Change this code to:
pub struct Foo { // note `pub`
...
}
pub fn make_foo() -> Foo {
...
}
The `visible_private_types` lint has been removed, since it is now an
error to attempt to expose a private type in a public API.
Closes#16463.
RFC #48.

a `#[feature(visible_private_types)]` gate has been added.

The stability lint will now check code generated by macro expansion. It will allow to detect :
- arguments passed to macros using deprecated (and others) items
- macro expansion generating code using deprecated items due to its arguments (hence the second commit, fixing such issue found in libcollections)
Checking is still done at expansion, but it will also detect a macro explicitly using a deprecated item in its definition.
- Don't attempt to autoderef `!`. The `Deref`/`DerefMut` trait lookup would generate a bunch of unhelpful error spew.
- Don't allow explicit deref of `!`, since later passes just ICE. This closes issue #17373
- Don't allow explicit index of `!`, since later passes just ICE. There does not seem to be an issue associated with this
There are currently two huge problems with the indent file:
1. Long list-like things cannot be indented. See #14446 for one example. Another one is long enums with over 100 lines, including comments. The indentation process stops after 100 lines and the rest is in column 0.
2. In certain files, opening a new line at mod level is extremely slow. See [this](https://github.com/mahkoh/posix.rs/blob/master/src/unistd/mod.rs) for an example. Opening a line at the very end and holing \<cr> down will freeze vim temporarily.
The reason for 1. is that cindent doesn't properly indent things that end with a `,` and the indent file tries to work around this by using the indentation of the previous line. It does this by recursively calling a function on the previous lines until it reaches the start of the block. Naturally O(n^2) function calls don't scale very well. Instead of recalculating the indentation of the previous line, we will now simply use the given indentation of the previous line and let the user deal with the rest. This is sufficient unless the user manually mis-indents a line.
The reason for 2. seems to be function calls of the form
```
searchpair('{\|(', '', '}\|)', 'nbW', 's:is_string_comment(line("."), col("."))')
```
I've no idea what this even does or why it is there since I cannot reproduce the mistake cindent is supposed to make without this fix. Therefore I've simply removed that part.
The following methods, types, and names have become stable:
* Vec
* Vec::as_mut_slice
* Vec::as_slice
* Vec::capacity
* Vec::clear
* Vec::default
* Vec::grow
* Vec::insert
* Vec::len
* Vec::new
* Vec::pop
* Vec::push
* Vec::remove
* Vec::set_len
* Vec::shrink_to_fit
* Vec::truncate
* Vec::with_capacity
* vec::raw
* vec::raw::from_buf
* vec::raw::from_raw_parts
The following have become unstable:
* Vec::dedup // naming
* Vec::from_fn // naming and unboxed closures
* Vec::get_mut // will be removed for IndexMut
* Vec::grow_fn // unboxed closures and naming
* Vec::retain // unboxed closures
* Vec::swap_remove // uncertain naming
* Vec::from_elem // uncertain semantics
* vec::unzip // should be generic for all collections
The following have been deprecated
* Vec::append - call .extend()
* Vec::append_one - call .push()
* Vec::from_slice - call .to_vec()
* Vec::grow_set - call .grow() and then .push()
* Vec::into_vec - move the vector instead
* Vec::move_iter - renamed to iter_move()
* Vec::push_all - call .extend()
* Vec::to_vec - call .clone()
* Vec:from_raw_parts - moved to raw::from_raw_parts
This is a breaking change in terms of the signature of the `Vec::grow` function.
The argument used to be taken by reference, but it is now taken by value. Code
must update by removing a leading `&` sigil or by calling `.clone()` to create a
value.

* I tried looking through `parser.rs` for an appropriate location for `expected_item_err` and ended up putting it just above the first use. Is there a better location?
* Did I add enough test cases? Too many? Should I add more cases for the original error message?
If you didn't have a trailing comma at the end of the variants, you could use
any type you wanted, but if you used a trailing comma the macro would
erroneously require the bits be a u32.
