9211348989 Make the parser accept 'if' as an alternative to 'when' in alt patterns.
Also fix the pretty printer, making it output 'if' instead of 'when'.

506a6ec38b Make syntax for impls less magical
The trick of interpreting parameters to the iface type as parameters
to the impl was just too magical.

aa5382bb13 split proto from fn_decl, as not all fn_decls know the proto.
this will address the (crashing) new test added.

057617c665 Parse iface items and interface references in impl items.
The (temporary) syntax is

    iface seq<T> {
        fn len() -> uint;
        fn iter(f: block(T));
    }

    // The 'blah<T>' can be left of to default the name of the
    // impl to seq<T>. The 'of seq<T>' can be left off when
    // not implementing a named interface.
    impl blah<T> of seq<T> for [T] {
        fn len() -> uint { vec::len(self) }
        fn iter(f: block(T)) { for x in self { f(x); } }
    }

e2e077c831 Remove trivial cast checker
I consider the added complexity not justified at this point, and it
interacts badly with the patches for issue #828. Feel free to discuss.

d529757515 Make polymorphic impl methods work
Something will still have to be done to the AST to make it possible to
say `x.foo::<int>()`, since currently field access never allows type
parameters.

cff6bdd036 Change syntax for impl
Move the name of the bundle to the front, allow type parameters (not
handled yet), and add a 'for' keyword:

    impl utils for int {
        fn str() -> str { int::str(self) }
        fn times(f: block()) { ... }
    }

7efef98901 Make uses of self in impls compile
Get rid of expr_self_call, introduces def_self. `self` is now,
syntactically, simply a variable. A method implicitly brings a `self`
binding into scope.

9a269a3aa8 Allow binding of nested patterns
See src/test/run-pass/nested-patterns.rs for some examples. The syntax is

    boundvar@subpattern

Which will match the subpattern as usual, but also bind boundvar to the
whole matched value.
