This is the next section of the guide, and it's on pointers. It's not done yet, as I need to write the section on ownership and borrowing, but I figured I'd share the rest now, to get feedback on the rest of it while I take some time to get that right.
The start of a testing guide. This PR relies on the crates and modules one because I shuffled some stuff around, so sorry about that.
I got stuck with how to import this name with cargo. @wycats and @alexcrichton , any ideas?
This is an alternative to upgrading the way rvalues are handled in the
borrow check. Making rvalues handled more like lvalues in the borrow
check caused numerous problems related to double mutable borrows and
rvalue scopes. Rather than come up with more borrow check rules to try
to solve these problems, I decided to just forbid pattern bindings after
`@`. This affected fewer than 10 lines of code in the compiler and
libraries.
This breaks code like:
match x {
y @ z => { ... }
}
match a {
b @ Some(c) => { ... }
}
Change this code to use nested `match` or `let` expressions. For
example:
match x {
y => {
let z = y;
...
}
}
match a {
Some(c) => {
let b = Some(c);
...
}
}
Closes#14587.

This is super, super WIP, but I'm going to go get lunch for a while, and figured I'd toss my work up here in case anyone wants to see my work as I do it.
This contains a new introductory section explaining the basics of pointers, and some pitfalls that Rust attempts to solve. I'd be interested in hearing how my explanation is, as well as if this belongs here. Pointers are such a crucial concept, I don't mind having a beginners' section on them in the main docs, even though our main audience is supposed to understand them already. Reasonable people may disagree, however.
The translation is based on an early version of tutorial.md, thus most
of entries have been marked as fuzzy and actually they are incorrect.
Now tutorial.md is planed to be replaced with guide.md, so I'd suggest
removing translation files for a while.

This eliminates the last vestige of the `~` syntax.
Instead of `~self`, write `self: Box<TypeOfSelf>`; instead of `mut
~self`, write `mut self: Box<TypeOfSelf>`, replacing `TypeOfSelf` with
the self-type parameter as specified in the implementation.
Closes#13885.

We now build the game at the end of the first section.
I wanted to do it as we went along, but it's too hard with these fundamentals
not in place. The rest will do the 'as we go' approach, but I think this is
better.
Simplify example in 5.2 to remove hidden `#[deriving(Show)]`. Traits haven't been introduced yet and now it's easier to just type in the code and expect it to work. Add in some examples for constructing the enum types. Explicitly expose `#![feature(struct_variant)]` in the code to make it more transparent, this bit me when I worked through the tutorial.
Add references in chapter 8 to later chapters describing `Rc`, `Gc` and `Send`. This is a simple fix for #15293.
Simplify vector indexing example in chapter 13 and removed hidden, unnecessary, code. Gave an example usage of the derived `Rand` trait in chapter 17.
Removed references to removed 'extra' crate.
Three small changes:
1. Re-organize headers in the Strings guide so they show up correctly.
2. build the strings guide with the other docs
3. include the strings guide in the list of guides
except where trait objects are involved.
Part of issue #15349, though I'm leaving it open for trait objects.
Cross borrowing for trait objects remains because it is needed until we
have DST.
This will break code like:
fn foo(x: &int) { ... }
let a = box 3i;
foo(a);
Change this code to:
fn foo(x: &int) { ... }
let a = box 3i;
foo(&*a);

5.2 Simplify example to remove hidden #[deriving(Show)].
Add example for constructing the enums.
8 Reference later sections describing rc, gc and send.
Fix for #15293.
13 Simplify BananaMania example to remove hidden code.
17 Gave an example using the derived Rand trait.
Removed references to removed 'extra' crate.
