This module provided adaptors for the old internal iterator protocol,
but they proved to be quite unreadable and are not generic enough to
handle borrowed pointers well.
Since Rust no longer defines an internal iteration protocol, I don't
think there's going to be any reuse via these adaptors.
This is preparation for removing `@fn`.
This does *not* use default methods yet, because I don't know
whether they work. If they do, a forthcoming PR will use them.
This also changes the precedence of `as`.
Change the former repetition::
for 5.times { }
to::
do 5.times { }
.times() cannot be broken with `break` or `return` anymore; for those
cases, use a numerical range loop instead.
Apparently yesterday wasn't my day, and I forgot to add the changes to
all the tests apparently, and in the end forgot the docs extra much.
Please documentation, forgive me, I really do love you, I hope you
forgive me.
Next time we'll meet tutorial, I promise to bring cookies and tea. I
really want to be best-friends-forever with you, <3.
XOXO
Adds a lint for `static some_lowercase_name: uint = 1;`. Warning by default since it causes confusion, e.g. `static a: uint = 1; ... let a = 2;` => `error: only refutable patterns allowed here`.
I removed the `static-method-test.rs` test because it was heavily based
on `BaseIter` and there are plenty of other more complex uses of static
methods anyway.
The confusing mixture of byte index and character count meant that every
use of .substr was incorrect; replaced by slice_chars which only uses
character indices. The old behaviour of `.substr(start, n)` can be emulated
via `.slice_from(start).slice_chars(0, n)`.
This is something that's only been briefly mentioned in the beginning of
the tutorial and all of the closure examples within this subsection
include only one expression between { and }.

The "4.3 Loops" section only describes `while` and `loop`. We then see `for`
used in a code sample at the end of the "13. Vectors and strings" section,
but it's explained for the first time only in the next section --
"14. Closures".
It is worth mentioning it in "4.3 Loops".
Although in the example function `each` works as expected with
rust-0.6 (the latest release), it fails to even compile with `incoming`
rust (see test/compile-fail/bad-for-loop-2.rs). Change the function to
return a `bool` instead of `()`: this works fine with both versions of
rust, and does not misguide potential contributors.

This removes the comparison to manual memory management examples,
because it requires too much existing knowledge. Implementing custom
destructors can be covered in the FFI tutorial, where `unsafe` is
already well explained.
This is some stuff which seemed to be missing to me (though I haven't read everything yet so hope I haven't missed the relevant section).
A similar addition for borrowing handles is needed, but #5720 stumped me.
Comments welcome.
The sentence "Remember that `(float, float)` is a tuple of two floats"
sounds like you've already read a section on tuples, but that section
comes later. Changing it to "Assuming that ..." makes it more about
taking the writer's word that the syntax is how tuples are defined.

In struct section of tutorial, make everything more coherent and
clear by always using "struct Point". Also, do not prematurely
introduce pointers and arrays. Fixes#5240
