Convert 'use' to 'extern mod'. Remove old 'use' syntax 2012-09-11 17:46:20 -07:00			`extern mod std;`
Correctly forbid upvars in nested impls, traits and classes Previously, resolve was allowing impls, traits or classes that were nested within a fn to refer to upvars, as well as referring to type parameters bound by the fn. Fixing this required adding a new kind of def: def_typaram_binder, which can refer to any of an impl, trait or class that has bound ty params. resolve uses this to enforce that methods can refer to their parent item's type parameters, but not to outer items' type parameters; other stages ignore it. I also made sure that impl, trait and class methods get checked inside a MethodRibKind thing so as to forbid upvars, and changed the definition of MethodRibKind so that its second argument is an optional node_id (so that required trait method signatures can be checked with a MethodRibKind as well). 2012-07-26 14:04:03 -07:00

Remove the class keyword 2012-08-15 18:46:55 -07:00			`struct siphash {`
Remove 'let' syntax for struct fields 2012-09-06 19:40:15 -07:00			`mut v0: u64,`
Convert class methods to impl methods. Stop parsing class methods 2012-09-07 19:04:40 -07:00			`}`
