Cannot parse global type constraints #5572

This code:

fn foo<T: ::cmp::Eq>(t: T) { }

fn main() { }

Errors with:

foo.rs:1:10: 1:12 error: expected `,` but found `::`
foo.rs:1 fn foo<T: ::cmp::Eq>(t: T) { }

The text was updated successfully, but these errors were encountered:

Hey folks, This patch series does some work on the json decoder, specifically with auto decoding of enums. Previously, we would take this code: ``` enum A { B, C(~str, uint) } ``` and would encode a value of this enum to either `["B", []]` or `["C", ["D", 123]]`. I've changed this to `"B"` or `["C", "D", 123]`. This matches the style of the O'Caml json library [json-wheel](http://mjambon.com/json-wheel.html). I've added tests to make sure all this work. In order to make this change, I added passing a `&[&str]` vec to `Decode::emit_enum_variant` so the json decoder can convert the name of a variant into it's position. I also changed the impl of `Encodable` for `Option<T>` to have the right upper casing. I also did some work on the parser, which allows for `fn foo<T: ::cmp::Eq>() { ... }` statements (#5572), fixed the pretty printer properly expanding `debug!("...")` expressions, and removed `ast::expr_vstore_fixed`, which doesn't appear to be used anymore.
