34d7f05292 Major clean-up of std::io 
Use ifaces instead of objs, stop wrapping everything in two (or three)
layers of no-value-added indirection, and remove some of the more
pointless/outdated idioms from the code.

0e334c6839 Fold and re-evaluate expr in tag discriminant. 2012-01-10 15:59:57 -08:00
Kevin Atkinson
08abf8d37f Support explicit discriminant numbers on tag variants. 
Addresses issue #1393.

For now disallow disr. values unless all variants use nullary
contractors (i.e. "enum-like").

Disr. values are now encoded in the crate metadata, but only when it
will differ from the inferred value based on the order.

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.
