Good morning,
It's taken a long time, but I finally am almost done freeing libsyntax of `vecs_implicitly_copyable` in this pull request, but I'm running into some issues. I've confirmed that all but the last commit (which only disables `vecs_implicitly_copyable` pass the `check` tests. The last commit errors with this message, which makes no sense to me:
```
/Users/erickt/rust/rust/src/libcore/num/f32.rs:35:37: 35:43 error: expected `,` but found `=`
/Users/erickt/rust/rust/src/libcore/num/f32.rs:35 pub pure fn $name($( $arg : $arg_ty ),*) -> $rv {
^~~~~~
```
and this stack trace:
```

```
There also a bunch of new warnings that I haven't cleaned up yet: https://gist.github.com/erickt/5048251.
@nikomatsakis thought there might be some scary bug in the parser caused by moving a vector in the parser instead of copying it, which is why I'm filing this pull request before it's ready. Thanks for any help!

The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Installation
The Rust compiler currently must be built from a tarball, unless you are on Windows, in which case using the installer is recommended.
Since the Rust compiler is written in Rust, it must be built by a precompiled "snapshot" version of itself (made in an earlier state of development). As such, source builds require a connection to the Internet, to fetch snapshots, and an OS that can execute the available snapshot binaries.
Snapshot binaries are currently built and tested on several platforms:
- Windows (7, Server 2008 R2), x86 only
- Linux (various distributions), x86 and x86-64
- OSX 10.6 ("Snow Leopard") or greater, x86 and x86-64
You may find that other platforms work, but these are our "tier 1" supported build environments that are most likely to work.
Note: Windows users should read the detailed getting started notes on the wiki. Even when using the binary installer the Windows build requires a MinGW installation, the precise details of which are not discussed here.
To build from source you will also need the following prerequisite packages:
- g++ 4.4 or clang++ 3.x
- python 2.6 or later (but not 3.x)
- perl 5.0 or later
- gnu make 3.81 or later
- curl
Assuming you're on a relatively modern *nix system and have met the prerequisites, something along these lines should work.
$ curl -O http://static.rust-lang.org/dist/rust-0.5.tar.gz
$ tar -xzf rust-0.5.tar.gz
$ cd rust-0.5
$ ./configure
$ make && make install
You may need to use sudo make install if you do not normally have
permission to modify the destination directory. The install locations
can be adjusted by passing a --prefix argument to
configure. Various other options are also supported, pass --help
for more information on them.
When complete, make install will place several programs into
/usr/local/bin: rustc, the Rust compiler; rustdoc, the
API-documentation tool, and rustpkg, the Rust package manager and build system.
